Here's a task that repeats every month in most accounting firms that handle VAT clients.
Take the purchase and sales records. Open the BIR RELIEF system. Enter the data row by row into the format the system needs. Export the DAT file. Check it. Do it again if something doesn't match.
BIR RELIEF is how the BIR cross-references VAT data across taxpayers — it's a reconciliation system, and it needs data in a specific format. Getting your records into that format manually is the slow part.
We built a converter that does this step for you. Your team keeps records in Excel as they already do. The converter reads those records and outputs a DAT file in the format the RELIEF system expects. No row-by-row reformatting. No manual data entry into the grid.
Your team still reviews the output before it goes anywhere. But they're reviewing a finished file, not building one.
