    Billing methods

    Bill the way each contract says

    Pick a method to see how the bill grows. One contract can mix methods, such as milestones for design and unit rates for site work.

    Bill a fixed share when a stage is signed off, such as design approval, delivery or commissioning.

    Bill the share of work finished, measured by cost, hours or physical progress.

    Measure quantities done against the bill of quantities and bill at contract rates.

    Bill hours and materials used, with agreed mark-ups and caps.

    See the gap between billed and paid

    The blue line is what you have billed, the gold line what the client has paid. The shaded gap is money owed to you. Example project.

    Retention

    Never forget money held back

    Retention is often 5% to 10% of every bill, and easy to lose track of over a long project. The ERP holds it by contract and reminds you on the release dates. Example figures.

    FAQ

    Progress billing questions

    Answers for owners, finance heads and project managers.

    What is progress billing?

    Progress billing means invoicing a client in stages as work is done, rather than once at the end. Each bill covers the work completed since the last one, so cash comes in while the project is still running.

    What is a running account (RA) bill?

    An RA bill is a cumulative progress bill used on Indian and Gulf contracts. It shows total work done to date, subtracts everything billed before, then deducts retention, advance recovery and taxes to arrive at the amount payable now.

    How is retention handled?

    A percentage of each bill, often 5% to 10%, is held back by the client. The ERP tracks retention by contract and reminds you when it is due, usually half at handover and half after the defects liability period.

    Can it recover mobilisation advances?

    Yes. You set the rule, such as a fixed % of each bill until the advance is cleared, and every RA bill deducts it automatically.

    Which billing methods are supported?

    Milestone, percentage of completion, BOQ or unit rate, and time and material. Different contracts, or different parts of one contract, can use different methods.

    Can clients approve bills online?

    Yes. Clients or their consultants can review measurements and photos, add comments and approve through a portal or a link on WhatsApp or email.

    Does it handle GST, e-invoicing and TDS?

    Yes. Bills become GST tax invoices with e-invoice IRN and QR codes, and TDS deducted by the client is tracked against each bill. VAT is supported for UAE, UK and other regions.

    What is over billing and under billing?

    Over billing is when you have billed more than the work your costs say is done; under billing is the reverse. Linking billing to job costing shows both, so cash and profit are not misread.

    How long does setup take?

    About 5 weeks, including one billing cycle run in parallel with your current method.
