The mandatory capabilities in Israeli invoicing software: allocation number, uniform format export, document types, linked credit notes, accountant access, export.
Key takeaways
- The allocation number is the first capability to check, and it is checked in a demo rather than a statement.
- Uniform-format export is what your accountant and the authorities ask for; a PDF is not a substitute.
- A credit note not linked to its original is what breaks reconciliation at year end.
- Export is a requirement rather than a convenience, because document retention is the business's obligation.
Israeli invoicing software is measured on seven capabilities: allocation numbers, uniform-format export, every document type, a credit note linked to its original, accountant access, data and document export, and a VAT report. Everything else is preference. These are not - and a missing one surfaces exactly when it becomes a problem.
This is an operational description, not advice. The regulatory references here describe requirements published on Israel Tax Authority pages; for any decision on the subject, consult an accountant or tax adviser and the official page.
The seven capabilities, and what to check in each
| Capability | Why it is mandatory | How to check it |
|---|---|---|
| Allocation number | An invoice above the threshold without one affects the customer's input VAT deduction | Issue a real document above the threshold and watch the number return |
| Uniform-format export | This is what is requested for audit and for data transfer | Ask to generate the files during a trial and open them |
| Every document type | Tax invoice, receipt, invoice-receipt, credit note, payment demand, quote | Issue one of each |
| Credit note linked to its original | Without the link, reconciliation breaks and proving what was cancelled is hard | Issue a credit note and check it points at the invoice |
| Accountant permissions | Saves file handovers and prevents duplicate versions | Invite them and they will tell you what is missing |
| Data and document export | Retention is your obligation; a system with no export is a trap | Export everything and open it elsewhere |
| VAT report | The basis for periodic filing | Run the report on trial data |
Two rows look technical and are the most practical. A linked credit note is what lets you answer "what exactly was cancelled" without searching. And export decides whether you can change systems in two years or are locked in.
The allocation number: what it is, and what to check
An allocation number is an identifier obtained from the Israel Tax Authority before issuing a tax invoice above a given threshold, under the Israeli invoice model. The threshold and the dates have been updated more than once, so the binding figure should be read from the Tax Authority's official page - not from an article and not from a marketing page.
What matters for choosing a system, independent of the threshold:
- The process should happen automatically, at document issue time, against Tax Authority servers.
- You need to know the failure behaviour: document blocked, saved as a draft, or issued without a number.
- You need to know where the number appears on the document and in reports.
- And you need to know who handles a rejection - you or support.
The technical side is documented in allocation numbers for developers, and handling rejections in a rejected allocation number.
What is the uniform format, and why is a PDF not enough?
The uniform format is a defined export format for bookkeeping data, not a document for printing. It exists so that whoever reviews the data can read it consistently across different systems - which is exactly why a PDF does not fill the role: it cannot be validated automatically.
What to check in a system:
- That the files can be generated from inside the system, without contacting support.
- That the export covers the period being asked for, not only the current month.
- That the files open and parse - worth testing once during a trial rather than on the day you need it.
The structure and its fields are documented in the BKMVDATA file and the uniform format, and the online VAT report in the PCN874 VAT report.
How do you know the system fails one of these?
Usually you do not find out while choosing but at the wrong moment, so it is worth knowing the signs:
- Somebody produces a document by hand in Word because the type is missing from the system. That is row 3 in the table.
- The accountant asks for a file and you send screenshots. That is rows 2 and 6.
- At year end you are hunting for which invoice was cancelled. That is row 4.
- Every month somebody re-keys data from one system into another. That is a sign there is no usable export.
- A customer complains they cannot deduct input VAT. That is row 1, and the most expensive of them all.
If one of those five happens in your business today, the problem is not the person keying data - it is the system.
Capabilities that are preference, not requirement
Worth separating so you do not pay for what you do not need:
- Inventory, till, billable hours, CRM. Important to whoever needs them, not mandatory.
- Digital signature. Very convenient; you can work without it.
- A mobile app. Matters in the field, not at a desk.
- Sales pages. A sales channel, not an accounting requirement.
- Foreign currency and English. Mandatory if you sell abroad, irrelevant otherwise.
- An API. Mandatory if you plan a connection to another system, otherwise not.
The simple rule: if the absence creates a problem with an authority or with your accountant, it is a requirement. If it creates inconvenience, it is a preference.
It is worth remembering these capabilities do not depend on business size. A sole trader issuing five documents a month is subject to the same requirements as a company issuing a hundred - the only difference is how often it touches them. So even a small, cheap system has to meet all seven, and if it does not, the saving is imaginary.

Frequently asked questions
What do you check first in Israeli invoicing software?
The allocation number, in a demo rather than as a question. Ask to issue a real document above the threshold and watch the number return, and ask what happens when the request is rejected. A system without a clear answer to both will create a problem with your customers.
Is a PDF invoice enough for my accountant?
For viewing the document itself it is, but for audit and data transfer a defined, machine-readable export format is requested. So a system needs to generate those files itself, and it is worth testing that once during a trial.
What if the system offers no export?
That is a reason not to choose it. Document retention is the business's obligation, and a system you cannot extract data from makes that obligation dependent on a vendor. Check export before joining, because afterwards you have no leverage.
Credit notes - why does linking matter?
Because without a link there is no simple way to show which invoice was cancelled and for how much. It surfaces in monthly reconciliation and at year end, when you are trying to explain a gap. A system that links automatically removes that search entirely.
