Planning Software for Manufacturing — What MRP Software Actually Does
If you're running a small manufacturing business, MRP planning software can transform how you manage materials, production, and costs. Here's exactly what it does — and why spreadsheets can't keep up.
Running a small manufacturing business means managing a lot of moving parts at once. Materials to reorder. Production runs to schedule. Customer orders coming in across multiple channels. Costs to track before tax time turns into a crisis.
Most makers start by managing all of this in spreadsheets. And for a while, it works. But as order volume grows, spreadsheet-based systems start to show their limits — manual entry errors, stock counts that don’t reflect reality, recipe costs that get stale as material prices change.
That’s the problem planning software for manufacturing — more commonly known as MRP software — is built to solve.
This guide covers exactly what MRP planning software does: the features it provides, how each one applies to small-batch manufacturing businesses, and how it compares to managing those same tasks in a spreadsheet. We also compare the main options for small makers so you can choose the right fit.
If you’re looking for the case for why MRP matters for small manufacturers, this overview of MRP systems covers five key reasons.

What is manufacturing planning software?
Manufacturing planning software — often called MRP software, short for Manufacturing Resource Planning — is a system designed to help manufacturing businesses manage their materials, production schedules, and costs in one connected place.
In the past, MRP software meant enterprise-level tools built for large factories with complex production lines — think Sage or NetSuite. These days, there are purpose-built MRP solutions scaled for small and medium-sized manufacturers. Whether you’re making candles, soap, cosmetics, jewellery, or bath and body products, there’s software designed specifically for how you work.
Where MRP software differs from a generic inventory app is in how everything connects. Your material stock levels feed into your production runs. Your production runs update your finished goods inventory. Your finished goods inventory flows through to your order fulfilment. Everything talks to everything else — so you’re not manually reconciling numbers across three different spreadsheets.
Spreadsheet vs. MRP software: what’s actually different?
Before getting into the features, it helps to see exactly where spreadsheets fall short compared to purpose-built planning software:
| Task | In a spreadsheet | With MRP software |
|---|---|---|
| Check current stock | Manual count or formula lookup | Live dashboard, updated automatically |
| Cost a recipe | Manually enter material quantities × prices | Automatic calculation from bill of materials |
| Update costs when a material price changes | Manually update every recipe that uses it | Automatic — one price update cascades everywhere |
| Track what you can make with current stock | Complex formulas, easy to get wrong | Instant max-manufacture calculation |
| Assign production runs to staff | Separate tracking system or sticky notes | Built-in manufacturing orders |
| Calculate COGS for tax | Hours of manual work | Pull a report |
| Know when to reorder materials | Requires constant monitoring | Low-stock alerts and reorder thresholds |
| Track orders across Etsy + Shopify | Two separate tabs at minimum | Automatic sync from each channel |
The difference isn’t just convenience. Each of those gaps is a place where errors creep in, costs get underestimated, or decisions get made without accurate data.
What can MRP planning software do for your manufacturing business?
1. Real-time material inventory tracking
The foundation of any MRP system is knowing exactly what you have on hand — not what you had last week when you did a manual count.
With MRP software, every time you record a production run, the materials you used are automatically deducted from your inventory. Every time you receive a delivery, stock levels update immediately. The result is a live picture of what’s on your shelf at any moment.
For a candle maker managing ten different fragrance oils, three types of wax, and multiple wick sizes, that live inventory is critical. Running out of fragrance oil mid-batch doesn’t just waste wax — it delays the entire production run and potentially pushes customer orders back.
MRP software also lets you set reorder thresholds for each material. When wax drops below a certain level, you get an alert — or the system automatically generates a purchase order — long before you’d actually run out. That’s the difference between proactive restocking and scrambling.
2. Bill of materials and recipe costing
A bill of materials (BOM) is the recipe for your product — every ingredient, component, or material, with the exact quantity used per unit or batch.
MRP software lets you build BOM records for each product, then uses those records to:
- Calculate exactly how much each product costs to make (automatically updated when material prices change)
- Show how many units you can produce from materials currently in stock
- Generate pick lists for production runs so your team knows what to pull
The costing piece is where many makers discover they’ve been underpricing. A cold-process soap maker who buys lye, oils, fragrance, and packaging from four different suppliers might estimate their cost per bar at $2.50. When they build a BOM in MRP software and track actual material costs over a few months, they often find the real cost is closer to $3.80 — once you account for waste, yield variation, and all the smaller materials that didn’t make it into the original estimate.
With MRP software, your recipe costs update automatically whenever you record a new purchase price for a material. You always know your current margins, not your margins from six months ago.

3. Production scheduling and manufacturing orders
A production schedule is your plan for what gets made, when, and in what sequence. MRP software makes this manageable.
When an order comes in, you can create a manufacturing order (MO) that:
- Specifies which product to make and how many units
- Lists the exact materials needed (pulled from your BOM)
- Checks whether you have enough stock to start
- Assigns the run to a team member or production date
- Tracks progress through the production process
For a cosmetics maker doing custom orders alongside standard collection pieces, this kind of scheduling visibility is the difference between a smooth week and a chaotic one. You can see at a glance which orders are in production, which are waiting on materials, and which are ready to ship — without chasing anyone for an update.
Production scheduling software also helps you catch potential problems before they happen. If you have three orders all needing the same carrier oil by Friday and only enough stock for two, you’ll see that conflict on Monday — not Thursday night.
4. Order management and demand tracking
Most MRP software for small manufacturers connects directly to the channels you sell through — Etsy, Shopify, Amazon, and others. Orders sync automatically rather than requiring manual entry.
Once orders are in the system, you can:
- Track each order’s status through production and fulfilment
- Set target completion dates and monitor whether you’re on track
- See which products are selling fastest and plan production accordingly
- Group orders by product to batch production runs more efficiently
For a maker selling across Etsy and Shopify simultaneously, this means one place to manage everything. No more checking two platforms and maintaining a separate fulfilment spreadsheet — or missing an order because it came in through a channel you hadn’t checked.
Demand tracking over time also helps you forecast. If your beeswax candles reliably triple in sales volume every October through December, you can use that data to front-load your material ordering in September — rather than scrambling to restock in the middle of your busiest period.

5. Cost tracking and COGS reporting
Cost of goods sold (COGS) is what it actually cost you to produce the items you sold. It directly affects your gross profit — and it’s what the IRS wants to see at tax time.
In a spreadsheet, calculating COGS means pulling purchase records, applying them against sales data, and doing a lot of manual reconciliation. Most makers either skip it or end up with estimates that don’t hold up.
MRP software tracks COGS automatically as you go. Because it knows the cost of every material in your BOM, and it records every production run against those costs, it can generate accurate COGS reports for any time period.
Come tax time, instead of hours spent reconstructing costs from receipts and order histories, you pull a report. For many makers, that single feature alone justifies the monthly subscription cost.
Beyond tax time, real-time cost tracking helps you make better pricing decisions throughout the year. If your raw material costs have crept up 15% over the past quarter, you’ll see that reflected in your margins before it becomes a problem — not after.

6. Supply chain and reorder management
Raw material availability is what keeps production running. MRP software helps you stay on top of your supply chain without constant manual monitoring.
Key features include:
Reorder thresholds: set a minimum stock level for each material. When inventory drops below that level, you get an alert.
Supplier lead times: track how long each supplier typically takes to fulfil an order. The system can factor this into your reorder timing — alerting you to reorder before you actually need the material, not after you’ve run out.
Purchase order tracking: record incoming deliveries against purchase orders so stock levels update accurately.
Low-stock visibility across all materials: see at a glance which materials are running low, rather than discovering it mid-production run.
For a bath and body product maker sourcing shea butter, essential oils, sodium hydroxide, and packaging from different suppliers — each with different lead times — this kind of supply chain visibility isn’t just convenient. It’s what keeps production from stalling.
Cloud-based vs. on-premise manufacturing planning software
Most small makers today choose cloud-based MRP software, and for good reason. But it’s worth understanding what you’re actually choosing between.
On-premise MRP means software installed on your own servers or computers. You pay a large upfront licence fee, maintain the software yourself (or pay someone to), and access it only from machines where it’s installed. This used to be the default for large manufacturers with IT departments. For a sole trader or small team making candles or skincare products from a home studio, on-premise software is almost never the right fit.
Cloud-based MRP runs in a browser. You log in from anywhere — your laptop, phone, or tablet — and your data is always current. Updates happen automatically, and there’s no server to maintain. Pricing is typically a monthly or annual subscription. This is what purpose-built tools like Craftybase use.
For small-batch makers, cloud-based software wins on every practical dimension:
- No upfront cost spike — just a predictable monthly subscription
- Access your stock levels and production queue from the shop floor or on the road
- Automatic backups, so a crashed laptop doesn’t wipe your records
- Integrations with Etsy and Shopify work natively in the browser
What about AI-driven planning in 2026? Some MRP platforms are starting to incorporate AI features — demand forecasting, anomaly detection in stock levels, automated reorder suggestions. For large manufacturers with years of sales data, these features can add real value. For most small-batch makers, the fundamentals matter more: accurate recipe costing, real-time material tracking, and reliable channel integrations. AI features are a nice-to-have, not a reason to choose a platform.
Comparing MRP software options for small makers
Not all MRP software is built for small-batch makers. Here’s how the main options compare for sole traders and small teams making physical products DTC.
Craftybase
Built specifically for small-batch makers selling DTC. Craftybase covers everything in this guide — real-time material tracking, BOM costing, production scheduling, multi-channel order management, and COGS reporting. It connects to Etsy, Shopify, Amazon, and other platforms natively.
Pricing is designed for sole traders and small teams, not enterprise budgets. The interface is built around the way makers actually work: recipes, material batches, finished goods, and sales channels. COGS reporting and Schedule C support are built in as core features.
Best for: candle makers, soap makers, cosmetics producers, jewellery makers, bath and body brands — anyone making small-batch physical products and selling DTC online.
Katana MRP
Katana is a well-regarded MRP platform aimed at growing manufacturing businesses. It handles multi-level BOMs, manufacturing orders, and shop floor control with more depth than most small-business tools. It also integrates with QuickBooks and Xero for accounting.
The tradeoff is pricing and complexity. Katana is positioned for businesses with multiple staff, workshop operations, and larger order volumes. A solo maker or a two-person team will likely find it more than they need — and priced accordingly.
Best for: small-to-medium manufacturers with growing teams who need deeper production floor management and accounting integrations.
Fishbowl Manufacturing
Fishbowl is a well-established manufacturing software built primarily around QuickBooks integration. It’s designed for businesses that already run QuickBooks and need manufacturing-specific features — work orders, BOMs, warehouse management — layered on top.
It’s a bigger investment than most small makers need: higher price point, requires Windows (desktop software), and the learning curve reflects its enterprise roots. If your business runs on QuickBooks and you have the budget and team for it, Fishbowl is capable. For a solo maker or DTC brand, the cost and complexity rarely make sense.
Best for: established manufacturers already on QuickBooks who need deep inventory and warehouse management, with IT resources to support implementation.
Which one is right for you?
If you’re a small-batch maker — selling small-batch or small-run physical products through Etsy, Shopify, or your own store — Craftybase is purpose-built for your situation. The features match what you actually need, the pricing fits a small business budget, and you don’t need IT support to set it up.
If you’re running a larger operation with staff across multiple production areas and need deeper accounting integration, Katana or Fishbowl may be worth evaluating.
How to evaluate planning software for manufacturing
When evaluating options for a small manufacturing business, look for:
Made-for-makers pricing: enterprise MRP starts at thousands per month. Small-business solutions like Craftybase are priced to make sense for sole traders and small teams.
E-commerce integrations: if you sell on Etsy, Shopify, or Amazon, make sure the software connects directly so orders sync automatically.
Bill of materials depth: can it handle multi-level BOMs? (Products made from sub-assemblies, which are in turn made from raw materials.) This matters if your products have any component complexity.
COGS and tax reporting: built-in COGS reporting saves makers hours at tax time. Check that it’s included as a core feature, not locked behind a higher plan.
Mobile access: if you’re on the shop floor or at a market, can you check stock or log production from your phone?
Support and onboarding: the initial data entry (loading your materials, recipes, and products) is the steepest part of getting started. Good support during that phase makes a significant difference.
Frequently Asked Questions
What is manufacturing planning software?
Manufacturing planning software — also called MRP software (Manufacturing Resource Planning) — is a system that helps businesses manage materials, production, and costs in one connected place. Where it differs from a basic inventory app is that it understands your production process: when you record a batch of candles, it automatically deducts the fragrance oil, wax, and wicks used, updates your finished goods count, and logs the production cost against your orders. Purpose-built options for small-batch makers now exist alongside the traditional enterprise tools.
What is the best MRP software for small business?
For small-batch makers selling DTC — candle businesses, soap makers, cosmetics producers, jewellery designers — Craftybase is purpose-built for your situation. It covers recipe costing, real-time material tracking, production scheduling, multi-channel order management, and COGS reporting, all priced for sole traders and small teams. Katana is a strong choice for businesses with larger teams and more complex production floor needs. Fishbowl suits established manufacturers already running QuickBooks. Most solo makers and small DTC brands find Craftybase the right fit from day one.
Can I use MRP software if I'm a one-person business?
Yes — and many solo makers get more value from it than larger businesses, because the time savings hit harder when you're doing everything yourself. Small-business MRP software like Craftybase is designed for sole traders and small teams. You don't need IT support to set it up, and the pricing is built for businesses that don't have enterprise budgets. The main investment is the initial setup: loading your materials, building your recipes, and connecting your sales channels. After that, most of the ongoing work happens automatically.
What's the difference between MRP software and inventory management software?
Inventory management software tracks what you have on hand — stock levels, locations, and reorder points. MRP software goes further: it connects your inventory to your production process, so it understands that making one batch of soap uses specific quantities of lye, oils, and fragrance, and automatically updates stock levels when that batch is recorded. It also handles production scheduling, bill of materials costing, and COGS reporting — things a basic inventory app doesn't cover. For businesses that manufacture products, MRP software is the more complete solution.
How does MRP software help with COGS and tax reporting?
Because MRP software tracks the exact cost of every material in your bill of materials — and records every production run against those costs — it can calculate your cost of goods sold (COGS) automatically over any time period. Instead of manually reconstructing costs at tax time from purchase receipts and order histories, you pull a report. Craftybase includes COGS reporting as a core feature, making Schedule C preparation significantly less painful for small manufacturers who sell DTC.
Does MRP software work with Etsy and Shopify?
Small-business MRP solutions like Craftybase connect directly to Etsy, Shopify, and other platforms. Orders sync automatically — no manual entry required. This means your inventory levels, production queue, and fulfilment status all update as orders come in, regardless of which channel they came from. If you sell through multiple channels, this integration alone can save 30–60 minutes a day compared to manually reconciling orders across multiple dashboards.
