How Can Our Opticians Check Lab and Frame Supplier Invoices Against the Jobs We Actually Ordered?

Opticians rarely check lab and frame supplier invoices line by line. We match invoice lines to jobs and orders and flag overcharges, duplicates and gaps.

Quick answer — TL;DR

Supplier invoices go unchecked because a lab statement can list hundreds of lines by job number and product code, and nobody has time to compare them with what was ordered. We build a check that reads each invoice or statement, matches every line to a job or frame order, compares prices with your agreed terms and flags duplicates, overcharges and items you never received, for a person to query.

A statement nobody reads line by line

At the end of the month, each lab sends a statement. Frame suppliers send invoices with each delivery and a statement later. The owner glances at the totals, sees they look roughly normal and pays. Checking each line against the jobs ordered would mean opening the practice system for every job number and comparing lens codes, coatings and prices by hand.

So small errors slip through: a coating charged that was not ordered, a job billed twice, an agreed discount not applied, a remake charged when it should have been free.

Why checking never happens

  • Statements are long and arrive as PDFs in varying formats.
  • Lab product codes do not always match how the practice describes the job.
  • Agreed prices and discounts are in an old email or a price file.
  • Remakes and warranty jobs should be charged differently, but are not flagged on the invoice.
  • Frame deliveries are not reconciled against orders on arrival.

What unchecked invoices cost

Type of errorHow it usually slips through
Duplicate chargeSame job appears twice across two statements
Wrong priceAgreed discount or price list not applied
Extras not orderedCoating or tint added by mistake
Remake charged in fullWarranty or non-adapt terms not applied
Frame invoiced but not receivedDelivery not checked against the invoice

Individually these are small. Across a year of statements from several labs and suppliers, they are worth checking, and suppliers generally correct genuine errors when they are shown them clearly.

How we build invoice checking

  1. Invoices and statements are collected from a dedicated email address, and read by a document parser, including PDFs, and turned into line items.
  2. Each line is matched to a job or frame order in your practice system by job number, order reference or patient.
  3. Prices are compared with your agreed price list or terms for that supplier, which we load once and you can update.
  4. Remakes and warranty jobs, where they are recorded in your system or remake log, are checked against the charge.
  5. Duplicates across statements, lines with no matching job and frames invoiced but not received are flagged.
  6. A person reviews the flagged lines, and a query to the supplier is prepared listing each one with its job reference.
  7. Approved invoices can be passed to your accounts package, such as Xero, for payment.

We do not negotiate with your suppliers or decide what they should charge. The check shows where invoices differ from what you ordered and agreed.

Month end, differently

Statements are checked line by line without anyone reading them. The owner sees a short list of genuine questions instead of a long PDF. Queries go to suppliers with clear evidence, which tends to get them resolved quickly. And frame deliveries are reconciled against orders, so the stock record stays accurate.

It also gives you better information when terms come up for renewal. A year of checked invoices shows exactly what you bought from each lab, at what prices, and how often corrections were needed, which is a far stronger starting point for a conversation with a supplier's account manager than a rough sense of what you spend.

Does this sound like you?

  • Supplier statements are paid after a glance at the total.
  • Nobody compares lab invoice lines with jobs ordered.
  • Agreed discounts are not checked on invoices.
  • Remakes may be charged in full without anyone noticing.
  • Frame invoices are not checked against deliveries.

FAQ

Frequently asked questions

Still have a question?

Ask us directly — a senior engineer will get back to you.

Ask about your project

Can it read our labs' PDF statements?

Yes, in most cases. Each supplier's format is set up once, and unusual layouts are checked by a person at first.

Does it need our price lists?

Yes, for price checking. We load them once and you update them when terms change.

Will it pay suppliers automatically?

No. It checks invoices and passes approved ones to your accounts package. Payment stays with you.

Does it work with our practice system?

It needs job and order records, which we read through your practice system's API or exports.
