Sales tax software for Deltek Costpoint

Deltek builds Costpoint for government contracting, aerospace and defence, and its tax model matches: a tax code with a rate you enter, linked to a project. Whether a sale is exempt depends on who is buying, and that answer changes by state. Commenda resolves it per customer, holds the document, and files.

Integration connection between platform and Commenda

Manage exemption certificates end to end

Federal agencies are exempt by law in Texas and do not apply for exemption. Another state's government agency is not exempt there. Commenda resolves that per customer and per state, and holds the document behind it.

Calculate tax without typing rates

In Costpoint a tax code is a rate you enter yourself, described in Deltek's help as usually a state or province. Commenda maintains rates across 14,000+ US jurisdictions and 70+ countries.

One exposure figure across every entity

Costpoint's sales and VAT report covers the entity you are in. Commenda consolidates every entity into one exposure figure per state, with alerts at 80% of a registration threshold.

What Costpoint handles, and what it hands back

Deltek positions Costpoint as ERP for government contracting, aerospace, and defense, and its tax model is built the same way, per project and per organisation. The figures below come from Deltek's own published Costpoint 8.1 online help, on setting up sales tax for billing, the Manage Sales or Value Added Taxes screen, customer VAT information, the sales and value added tax report, and how its EU VAT lines are built, checked on July 30, 2026.

Calculate taxes globally on Costpoint using Commenda

Tax resolves per transaction against the ship-to or place-of-performance address, down to county, city, and district, with a product tax code on each line. Nobody maintains a tax code per jurisdiction and nobody types a percentage. Where a project bills a customer that is genuinely exempt, the line goes out exempt and the reason is recorded against it.

Manage your customers and exemptions in one place

An exempt government sale still needs evidence at the transaction. Texas accepts a completed exemption certificate or a purchase voucher in the government entity's name. Commenda stores that against the customer, validates it on upload, applies it automatically in the states where it holds, and keeps an audit log of when you started selling to that customer.

Track your global exposure from Costpoint

Costpoint links a tax code to a project. It does not tell you which states your project portfolio added up to. Commenda measures the same transactions against economic and physical thresholds in all 50 states and 70+ countries, and notifies you at 80% of a threshold. A questionnaire covers site offices and staff on customer premises, because neither shows up on an invoice.

Automatically remit transactions around the world

Returns are built straight from your Costpoint transactions, so nothing gets exported into a spreadsheet after the tax report tables have been updated. Filings go out across all 50 states on each state's required frequency, plus EU VAT with OSS and GST in APAC and Canada, with amendments where a period needs correcting. The liability and the filing confirmation post back to your ledger.

Consolidation

Why your customer's status decides your Costpoint tax position

For a government contractor the taxable question is rarely about the work. It is about who the customer is, which state they are in, and whether you can produce the document. Costpoint records the invoice. Commenda answers the question.

  • Federal, state, and local are three different answers

    Texas states that federal government entities, including all agencies, departments and branches of the military, are exempt by law and are not required to apply for exemption. Texas state and local entities are exempt the same way. Government entities of other states are not. So the same contract line can be exempt for one customer and taxable for the next, and the deciding factor is who is buying rather than what you sold. That resolves per customer per state, on live data, not on a tax code you set once.

  • Exempt by law still means a document on the transaction

    Even where the buyer never applies for exemption, the seller carries the evidence. Texas accepts a properly completed exemption certification or a purchase voucher in the government entity's name, and notes that a seller is not obliged to accept an exemption certificate at all. Costpoint gives you an Exempt check box and a certificate number field on the tax code. We store the document itself, validate it on upload, and keep the log that an auditor asks for.

  • Costpoint reports the entity you are standing in

    Its sales and value added tax report runs after you refresh the report tables, and the VAT side fills return lines rather than a return. Deltek also documents that Costpoint does not recognize both Sales and VAT tax for one customer, so a customer trading in two regimes becomes two customer records. Splitting a customer to satisfy a tax field is exactly the kind of thing that makes a group-level exposure number wrong. We read the transactions, not the customer count.

  • One ledger behind every entity and every contract vehicle

    Government contractors grow by acquisition, and each acquired entity brings its own registrations, its own back periods, and often its own system. Every source connects to one ledger across 100+ supported integrations, with each transaction carrying its origin. You get one exposure figure per state per entity, consolidated on one dashboard, and the registrations you are still carrying but no longer need are as visible as the ones you are missing.
