An invoice arrives in a director’s inbox on Friday afternoon. Another lands in WhatsApp. A third is attached to an email with no purchase order or explanation. By month-end, someone is chasing approvals, copying totals into a spreadsheet and trying to work out which costs include recoverable VAT.
Learning how to automate invoice approvals starts by fixing that workflow, not by adding another complicated finance system. The aim is simple: capture every invoice, match it to a clear approval rule, send only the right exceptions to a person, and keep an audit-ready record from receipt to payment.
Start with a clear approval policy
Automation cannot make an unclear approval process better. It will only move the confusion faster. Before choosing rules or software, decide who can approve which spend and what information must be present before an invoice can move forward.
For a small business, this may be straightforward. Routine supplier invoices can be approved by an operations manager, while larger purchases require a director. For an accountancy firm, the same structure may need to work across several client entities, each with different people, limits and VAT circumstances.
Your policy should answer four practical questions:
- Which invoices can be approved automatically?
- Who approves spend above each value threshold?
- What should happen when the invoice does not match a purchase order, contract or usual supplier pattern?
- Who can approve an exception, and who can release a payment?
Keep these rules proportionate. Requiring director approval for every €25 software subscription is not control. It is a bottleneck. Equally, auto-approving every invoice from a familiar supplier can create risk if the amount, bank details or VAT treatment changes.
Separate invoice capture from approval
The approval process starts when an invoice enters your records, not when somebody remembers to forward it. Give suppliers one or more reliable routes to submit documents, such as a dedicated email address, WhatsApp or a dashboard upload. The important part is that every route leads to the same processing queue.
Once received, the system should extract the supplier name, invoice number, date, due date, line items, net amount, VAT and gross total. It should also identify the invoice currency and retain the original document. This removes the repeated keying that creates most avoidable errors.
For Malta-based businesses, invoice capture must do more than read totals. It needs to classify VAT correctly for the transaction. A local purchase, an EU service, a reverse-charge transaction and an expense with non-recoverable VAT should not all be treated the same way simply because they came from the same supplier.
MyAccountant is designed around this practical starting point: submit invoices through the channel that suits your team, then let the platform extract data, categorise VAT and prepare records for review. Approval decisions are more reliable when the data reaching the approver is already complete.
Build rules around risk, not habit
The best way to automate invoice approvals is to auto-process predictable, low-risk invoices and route uncertainty to the person best placed to resolve it. That means using rules based on supplier, amount, category, entity, payment terms and supporting documents.
A recurring internet bill from an established supplier may pass through with minimal intervention if the amount is within an expected range. A new supplier invoice for €4,800, however, might require a purchase order, budget owner approval and director sign-off. Neither approach is universally right. The rule should reflect the financial risk and the way your business buys goods and services.
Set sensible thresholds. A founder-led consultancy may require approval above €1,000. A growing SME may use different limits for department heads, finance managers and directors. Accountancy firms should be able to apply distinct policies per client rather than forcing every business into one approval model.
Use supplier memory carefully. It is valuable when the system recognises a regular supplier and the usual account category, but it should not replace controls. Flag invoices where the amount is materially higher than normal, the invoice number appears duplicated or the payment details differ from previous documents.
Route exceptions quickly
An approval workflow succeeds or fails on its exceptions. Most invoices are routine. The ones that cause month-end delays are missing information, have unclear VAT treatment, arrive in a foreign currency or do not fit the expected spending pattern.
Do not send every invoice to the same person. Route each exception with a clear reason. For example, a project manager needs to confirm whether a contractor invoice relates to delivered work. An accountant may need to decide the VAT treatment of an EU software service. A director may need to authorise an unbudgeted purchase.
The request should contain enough context for a fast decision: the invoice image, supplier, amount, due date, category, VAT code, prior invoices if relevant and the specific reason it was flagged. “Please approve” is not useful. “Approve this €1,250 invoice from a new supplier with no purchase order” is.
Set reminders and escalation rules, especially for invoices approaching their due date. A reminder after two working days and escalation after five may be appropriate for a small team. Where early-payment discounts matter, use shorter windows. The goal is not to pester people. It is to prevent silence becoming an accounting problem.
Keep VAT and currency visible in the workflow
Approval is not only a spending decision. It also affects the accuracy of your bookkeeping and VAT return. If an invoice is approved using the wrong VAT category, the payment may be correct but your reporting can still be wrong.
This matters particularly for businesses in Malta dealing with EU suppliers and foreign-currency invoices. The approver should be able to see the original invoice currency alongside the euro value recorded in the books. Use a consistent conversion method and retain the original amount, exchange rate basis and document for audit purposes.
Where VAT treatment is uncertain, route the invoice to an accountant or finance reviewer rather than guessing. Automation should reduce routine work, not automate poor judgement. A properly designed system surfaces these cases early, while the supplier and transaction details are still easy to verify.
Protect the approval trail
A good approval process creates evidence without adding admin. Every invoice should have a clear history showing when it was received, what data was extracted, who reviewed it, what changed and when it was approved.
This is useful well beyond an audit. It helps when a supplier disputes a payment, a colleague asks why an expense was coded a certain way, or an accountant needs to review a VAT figure before filing. It also reduces dependency on one person’s inbox or memory.
Maintain separation between approval and payment where your team size allows it. The person confirming that a service was received should not necessarily be the only person able to add or amend supplier bank details and release funds. Small businesses cannot always split every role, but they can add practical safeguards for higher-value or unusual payments.
Test the workflow before relying on it
Start with a limited group of suppliers or one entity. Run real invoices through the process and watch where people hesitate. Are approval requests missing context? Are thresholds too low? Are invoices being routed to people who cannot make the decision? Is VAT being reviewed at the right point?
Measure a few useful outcomes: time from receipt to approval, number of invoices requiring manual correction, overdue invoices and the percentage processed without intervention. Do not judge success by how many rules you create. Judge it by whether month-end becomes faster and the exception queue becomes smaller.
Refine the rules after the first month. Supplier patterns change, teams grow and new types of costs appear. A workflow that is simple to adjust will remain useful. One that requires a major setup project for every change will soon be bypassed.
The right invoice approval process should feel almost quiet. Routine invoices move where they need to go, exceptions arrive with context, and your records are ready before month-end pressure builds. That is the point of automation: less chasing, fewer spreadsheets and more time spent making decisions that actually need human judgement.
