Invoices clients actually pay: a guide for bilingual firms
An invoice is the one document every client reads to the last line. For firms working in Arabic and English, a few choices decide whether it gets paid in a week or argued over for a month.
Firms spend weeks perfecting a memo and minutes on the invoice that follows it. Yet the invoice is the document every client reads to the last line — often the finance team rather than the person who instructed you. For firms that work in Arabic and English, a few deliberate choices make the difference between prompt payment and a long exchange of emails.
Decide the invoice language per client, not per firm
Some clients' finance departments need Arabic; others book everything in English. Set the language on the client, so every invoice to them is consistent, and make sure names — company, matter, contact — appear exactly as they are registered.
Put the matter first
Clients with several matters pay by matter. The matter number and a short matter title near the top let the finance team route the invoice without asking you which case it belongs to.
Name the person it is for
An "Attention" line with the responsible contact at the client stops invoices from sitting in a shared inbox. It is a small field that removes days from the payment cycle.
Make the work readable
Line items should describe work the client recognises: dates, who did it, and what was done. A short summary per lawyer — hours and rate — answers the question most finance teams ask first.
Be explicit about currency
If you invoice in one currency and the client pays in another, say which currency the invoice is payable in. If you show a converted figure for reference, show the rate and the date you used, and label it clearly as reference only.
Use a consistent numbering series
Sequential invoice numbers — with separate series where your accounting needs them — make reconciliation easy for both sides and look professional to auditors.
End with how to pay
Bank details, the reference to quote, and the due date should sit together at the end. A client who has to search for your IBAN will put the invoice aside for later.
Keep one template, well built
Rather than editing each invoice by hand, build a template once — sections in the right order, headings in the client's language, your bank details in the footer — and let every invoice follow it. Lexivo's invoice template builder exists for exactly this.
