    The Restaurant Back Office: Supplier Bills, Cash Purchases and VAT

    Supplier invoices that arrive as photos, cash handed over for urgent purchases and food cost known only in hindsight. How Nigerian restaurants and caterers can run a tight back office.

    A restaurant's dining room gets all the attention. The money is won or lost in the back office: what the kitchen bought this week, what it paid, and whether anyone can prove it. Whether you run one restaurant, a chain or a catering company, the same three leaks appear.

    Leak one: supplier bills that never become records

    Produce, protein, gas and drinks suppliers send invoices as photos in a chat, or on paper with the delivery. If someone has to retype them, most never become records. Set one rule: every bill is forwarded to one place on the day it arrives, checked against what was delivered, and approved before payment.

    Leak two: cash purchases with no trail

    Cash handed over for an urgent purchase disappears the moment it leaves the drawer. Replace it with a claims process: the person who spends photographs the receipt, it is categorised and approved, and they are reimbursed by transfer. See staff expense claims.

    Leak three: food cost known only in hindsight

    If purchases are recorded weekly, you can compare kitchen spend with sales every week and act while it matters: change a supplier, adjust a portion, reprice a dish. If they are recorded monthly, you find out when it is too late.

    Keep VAT filing-ready

    Restaurants charge VAT on sales and pay it on many purchases. When every bill and receipt is captured as it happens, the monthly VAT return is a report, not a reconstruction from bank statements.

    For chains and caterers

    • Track costs per outlet or per event, so one loss-making location cannot hide behind a busy one.
    • Set what a kitchen supervisor can approve alone, and what needs the operations manager or owner.
    • Invoice corporate catering clients promptly with clear terms, and track what they owe.

    How Billif helps

    Suppliers send bills to your Billif mailbox, or staff forward the photo, and OCR turns them into payables with the vendor, amount and due date. Staff purchases become claims with receipts, categorised by AI and routed for approval. Because every bill and receipt is captured as structured data, the VAT report is ready when you file.
