AP Automation for Manufacturers Who Can't Afford Errors.

In manufacturing, AP errors compound. A short-paid invoice strains a critical supplier relationship. A duplicate payment ties up cash. A missed price variance becomes a margin leak across the BOM. We build AI invoice matching that handles the specific complexity manufacturing AP teams face, multi-currency, components, substitutions, and MOQ logic.

The manufacturers reality.

Manufacturers buy from dozens of suppliers, often international, often in different currencies, often with substitutions when the original part isn't available. Three-way matching across invoice, PO, and GRN is mechanical work that takes hours and is exactly where errors creep in, wrong currency conversion, missed price variance, accepted substitution that doesn't match the PO spec.

Tuned for manufacturers.

01

Multi-currency, multi-VAT support

Invoices in GBP, EUR, USD, JPY, handled with the rate that applied on invoice date. Reverse-charge VAT on EU suppliers handled correctly post-Brexit.

02

Component-level matching

Each invoice line matched to PO line and GRN line. Part numbers, quantities, prices. Substitutions recognised against allowed-substitution rules.

03

MOQ and price-break awareness

Supplier MOQs and quantity-break pricing applied automatically. Variance from negotiated rates flagged before invoices post.

04

Cost code routing

Lines coded to the right BOM, work order, or overhead account at match time. Posts through to your ERP with correct allocations.

Things people in this industry ask us.

01How do you handle international suppliers?

Multi-currency is built in. Invoice currency is detected, FX rate at invoice date is applied (using HMRC daily rates or your accounting system's rates), and reverse-charge VAT is handled for EU suppliers per post-Brexit rules.

02What about MOQ and price-break logic?

Configurable per supplier. The system applies the right price break based on PO quantity, flags variances if the supplier invoices outside the agreed scheme, and handles MOQ adjustments where they appear on the invoice.

03Can it integrate with our existing ERP?

Yes, Sage, NetSuite, Dynamics, SAP Business One, and most custom ERPs. We read POs and GRNs, post matched invoices back with the right cost coding and approval state.

04What about supplier substitutions?

Allowed substitutions are configured per part or per supplier. The system recognises when an invoiced part is a recognised substitution for the PO part, applies the right pricing, and flags only substitutions that aren't pre-approved.

05How long until ROI?

Typically 3-6 months on hours saved alone. The bigger return is the reduction in costly errors, duplicate payments, missed price variances, supplier disputes resolved with full audit trail.
