14-day free trial · No credit card required
Everything you need to run your shop floor
From defining BOMs to shipping finished goods — with your accounting system in sync the whole way.
BOMs & Versioning
Multi-level, nested BOMs with optional components, cost lines, and version history. Define exactly how your products are assembled.
Build Execution
Plan builds, queue them up, execute with one click. Inventory auto-deducts, costs auto-calculate. Quick builds for simple assemblies.
Accounting Sync
Connect your accounting system, import items, and export builds as journal entries with inventory adjustments. Automatic.
Team & QA
Assign builds to team members, require quality review before finished goods hit inventory. Role-based permissions keep everyone in their lane.
Receiving & Lot Tracking
Track incoming inventory with purchase receipts and lot numbers. FIFO consumption ensures traceability from supplier to finished product.
Sales & Margins
Sync sales from your accounting system, track finished goods consumption, and see real margins per product — not estimates.

Every manual entry is a chance for an error. Every spreadsheet is a reconciliation waiting to happen.
Before
Manual Journal Entries
30 minutes per build hand-typing inventory adjustments into your accounting system. Every single time.
With Partsemble
Automated Accounting Sync
One click pushes accurate journal entries automatically. No manual work ever again.
Before
Stale Data Pricing
COGS calculated days later from memory and receipts. Margins are always a guess.
With Partsemble
Real-Time GAAP-Compliant COGS
Costs calculated and posted at build time using actual component prices.
Before
Inventory Mismatches
Your books say 50 units. Reality? You shipped 47. Reconciliation nightmares at month-end.
With Partsemble
Zero Reconciliation Headaches
Component consumption auto-deducts when you log a build. Books match reality.
Before
Component Confusion
Promising delivery dates without knowing if parts are in stock. Customers waiting.
With Partsemble
Instant Build Visibility
See exactly how many kits you can ship today before your customer asks.
Before
Spreadsheet Lot Tracking
Tracking lot numbers in a spreadsheet that's always out of date. No way to trace a finished product back to its components when a customer calls.
With Partsemble
Automated Traceability
Every receipt gets a lot number. FIFO consumption links components to builds automatically. Trace any product back to its source in seconds.

Built for small manufacturers
Whether you're producing food, formulating products, or assembling hardware — Partsemble adapts to your workflow.
Food & Beverage Producers
Manage recipes as BOMs, track ingredient lots for recalls, and keep COGS accurate as raw material prices fluctuate. From hot sauce to granola.
Health, Beauty & Supplements
Track batch numbers for compliance, manage multi-component formulations, and calculate true product costs across dozens of ingredients.
Electronics & Hardware Assemblers
Precision component tracking down to the unit. Nested sub-assemblies, supplier management, and QA review before finished goods ship.
Built for makers. Trusted by accountants.
Clean books aren't just nice to have. They're what keeps you out of trouble at tax time.
Clean Audit Trail
Every build creates a complete, timestamped record. Audit-ready from day one, not scramble-ready at year-end.
GAAP-Compliant COGS
Costs allocated at build time using actual component prices. No approximations, no surprises.
Bookkeeper-Friendly
Journal entries your accountant can read without a translation guide. Less time explaining, more time growing.

Advanced adds inventory receiving with lot tracking, supplier management, sales sync, and margin tracking. See the pricing section for full details.
Yes. Upgrade or downgrade at any time from your billing settings. Upgrades take effect immediately with prorated charges. Downgrades take effect at the end of your billing cycle. Cancel anytime with no fees or penalties.
A build is when you execute an assembly — Partsemble deducts the component inventory and adds the finished goods. Maker includes 50 builds/month, Pro includes 500. Advanced is unlimited with overage pricing beyond the included 2,000.
Advanced includes generous monthly allowances (2,000 builds, 200 receipts, 500 sales orders, 25 users). Usage beyond these limits is billed at a small per-unit rate. Product SKUs are unlimited up to 10,000 — beyond that requires custom pricing. The idea is simple: you're never blocked from working.
Yes. All data is encrypted in transit and at rest. We use industry-standard security practices including SSL/TLS encryption, secure authentication, and regular backups. Your accounting credentials are stored using Fernet symmetric encryption and never exposed to the frontend.
