1Start by exporting and counting
Pull every customer you have invoiced in two years and count how many have a complete tax record. That number is your project size.
The spreadsheet is not the problem. The problem is that everything the standard needs — customer tax details, structured line data, consistent numbering — lives in a spreadsheet as free text if it lives anywhere at all. Here is how the move actually goes.

Migrating dirty data into a new system produces a new system full of dirty data. Clean first, migrate second.
You need your open receivables live in the new system. Historical invoices can be archived as they are — you do not need to recreate them.
Do not delete it. Lock it, date it, store it, and stop writing to it. That gives you a clean cut-over point.
Everything here can be done before you commit to a provider or a system.
Our e-invoicing product is being built now, alongside the ERP, CRM and accounting systems our technology team already runs for UAE clients. Early-access clients get their requirements built into the core rather than bolted on afterwards, which is genuinely better for them and better for the product. Start with invoicing and add the rest when your business actually needs it.
GoldenKey is a business setup and compliance consultancy. We are not a Ministry of Finance Accredited Service Provider, and we do not claim to be one. Our software is built to work alongside the ASP you appoint. Scope, timelines and pricing are agreed in writing before any work starts.
Short, practical answers. If yours is not here, ask us directly — we answer even if you never become a client.
Export and clean your customer list first, then migrate open balances only, then cut over on a clean date and keep the spreadsheet as a locked archive.
No. History stays available as an archive. You only need open items live in the new system.
Usually a few weeks, and most of that is customer data cleanup rather than software work.
Implementation capacity gets scarce before every deadline. Starting now costs less and gets better attention.
No cost, no obligation. We tell you which phase you fall into and what you actually need.
GoldenKey covers every step — start, run, grow — under one golden roof:
