Best Project Management Software With Invoicing

What should you check before comparing invoicing features?

project management software with invoicing is a key topic in modern project management and teamwork. Check five things in this order: the billing model, the path from time to invoice, tax handling, currency handling, and the accounting handoff. A tool that fails the first two will not be rescued by a long feature list.

Billing model. Agencies bill in at least four ways: hourly, fixed fee, retainer, and milestone. A tool built for hourly work will fight you on retainers, and a retainer-first tool will feel heavy for a five-person studio billing by the hour.

Time to invoice. The question is not “can it create an invoice” but “how many clicks and how much re-keying between approved timesheet and sent invoice”. The good version is one screen: pick the project, pick the period, review the billable lines, adjust, send.

Tax. Line-item tax rates, tax groups, reverse charge, and exemption notes. If you sell across borders, this is where cheap tools break.

Currency. Multiple currencies on one invoice, a defined exchange-rate source, and a rule for who absorbs the difference. Many tools support a second currency and stop there.

Accounting handoff. A native sync to Xero or QuickBooks is worth more than a hundred CSV exports, because it removes the reconciliation step that month-end always loses.

What does each tool cost in 2026?

Prices below are list prices in USD checked in November 2026. Annual billing is cheaper on every tool in this table, and most vendors change prices without much notice, so treat the table as a starting point and confirm at checkout.

Two pricing mechanics deserve attention before the per-seat numbers. First, Teamwork’s invoicing sits on Accelerate, which requires at least five seats, so the real entry cost is 5 × $24.99, or $124.95 per month, not $24.99. Second, Productive and Paymo both discount annual billing meaningfully, and Paymo’s annual saving is advertised as up to 40%, which changes the ranking at the low end.

How does Paymo handle invoicing?

Paymo treats time as the source of truth, and invoicing as a report on it. Invoices are included on every plan, including the free plan, which is unusual and genuinely useful for a solo freelancer testing the workflow.

Paymo’s strength is the shortest path from tracked time to a sent invoice: log time against a task, mark it billable, select the period, review the lines, apply the rate, send. It also supports recurring invoices, estimates, expenses, and online payments, so a retainer client can be billed without leaving the tool.

The limits are the familiar ones for a mid-market tool. Tax handling is rate-based and manual; there is no e-invoicing format for countries that mandate one. Multi-currency invoicing exists, but the exchange-rate policy is yours to define, and the accounting sync relies on integrations rather than a native two-way ledger. For a design studio billing in one currency, none of that matters. For a consultancy invoicing three EU entities with reverse charge, it does.

How does Teamwork handle invoicing?

Teamwork is built for client-service teams, and its invoicing reflects that: billable time, budgets, and retainers feed invoices on the Accelerate plan and above.

The useful parts are budget awareness and retainer logic. A project can carry a time budget, the invoice can be generated from approved billable time, and the team can see how much of the retainer has been consumed before the invoice goes out. That combination is rarer than it sounds; many tools invoice well but cannot tell you whether the project is still profitable.

The trade-offs are price and gating. At $24.99 per user per month with a five-seat minimum, a ten-person team pays $249.90 monthly before add-ons, and multi-currency financial budgets only arrive on the Optimize tier, which is quoted. If you bill in two currencies, ask for an Optimize quote before you assume Accelerate is enough.

How does Productive handle tax and e-invoicing?

Productive is the strongest of the group for tax complexity. It applies tax per invoice line item, supports credit notes, can invoice multiple budgets in one document, and exports e-invoices in formats used in Germany, the Benelux, Spain, Italy, and Slovenia.

That last point is the practical differentiator. If your finance team has to produce XRechnung or Peppol-compliant documents, a tool that only generates a PDF pushes the compliance work back into a spreadsheet. Productive also handles currency conversion in advanced reports, which is what you need when the project budget is in euros and the client pays in dollars.

The cost is structural rather than financial. Productive is a full agency operating system: budgets, resourcing, CRM, profitability. Teams that only want invoices and tasks will find it heavy, and the entry tier at roughly $9–12 per user per month excludes invoicing; you need Professional at roughly $25–29. With a three-seat minimum, that is about $75–87 per month to start invoicing properly.

What about Scoro and Accelo?

Scoro and Accelo are quote-based, which is a signal about their buyers: agencies large enough to need a configured quote-to-cash process, not teams comparing list prices.

Scoro covers the full chain from quote to project to invoice, with strong time and resource planning. For an agency that sends proposals, converts them to projects, and bills against a retainer, the value is that nobody re-enters the same data three times. The trade-off is implementation effort: Scoro rewards configuration, and a five-person team will spend more time setting it up than it saves in the first year.

Accelo is built around service operations: retainers, tickets, and recurring revenue. If your revenue is a set of monthly retainers with overage, Accelo’s billing model matches how you actually sell. If your work is project-based, the model fights you, and the module pricing makes the comparison harder.

Both tools are worth a demo when your billing logic is genuinely complex. Neither is worth it when you send twelve invoices a month in one currency.

What does invoicing actually cost an eight-person agency?

Take an eight-person studio with six billable people, each billing 110 hours a month at $95 an hour. Monthly revenue is 6 × 110 × $95, or $62,700.

The spread between the cheapest and most expensive option is $1,257 a year, which is roughly thirteen billable hours. That is not the deciding number. The deciding number is what each tool saves in admin time and late payments.

Now price the manual alternative. Suppose invoices take six minutes each to assemble by hand and you send forty a month: 240 minutes, or four hours, worth about $380 at a $95 internal rate. Add the reconciliation step at month-end, two hours, and one late invoice a quarter at $8,000 with a 45-day delay. The software is not competing with its own price. It is competing with the cost of the spreadsheet.

How do tax and currency limits show up in practice?

They show up as a month-end argument. Here is a currency case first: you invoice a client €12,000 with a 30-day term. On the invoice date the rate is 1.08, so your ledger records $12,960. The client pays on day 34 at 1.05, and the bank credits $12,600. The $360 difference is a real loss that no project tool prevents, but a tool with a documented rate policy makes it visible and repeatable instead of mysterious.

Tax is the bigger risk. On the same €12,000 invoice with 20% VAT, the gross is €14,400, and the €2,400 is not your money. A reverse-charge B2B sale inside the EU moves the tax to the client and requires a note on the invoice. If your tool cannot store a per-client tax rule and print the note, someone will add it by hand, and eventually someone will forget.

Read the table as a filter, not a scorecard. If you invoice only domestically, the e-invoicing column is irrelevant and Paymo’s value case gets stronger. If you invoice into Italy or Germany, Productive’s formats may save more than the per-seat difference.

Which tool fits which business?

The pattern is boring and correct: match the billing model first, then the tax jurisdiction, then the price. Teams that start with price usually end up exporting CSVs into accounting software and paying twice for the same work.

What are the trade-offs of invoicing inside a project tool?

The benefit is context. An invoice raised next to the project carries the time entries, the budget, and the person who approved them, so a client query takes one screen instead of an archaeology session.

The cost is depth. Dedicated accounting software will always win on tax filing, statutory reporting, audit trails, and multi-entity consolidation. Project tools approximate those functions well enough for a small agency and not well enough for a finance department.

A hybrid is common and reasonable: invoice from the project tool, sync to the ledger, and keep statutory filing where it belongs. The failure mode is doing both by hand.

Where does Doitify fit?

Doitify is our product, so read this as disclosure. It is built as one workspace for projects, tasks, sub-tasks, checklists, owners, and due dates, with CRM, finance management, project documents, workload views, Gantt charts, and work and performance reports in the same system. Invoicing sits next to the project rather than in a separate module, which is the point: the client, the deal, the delivery, and the invoice share one record.

That architecture helps most when the same small team sells, delivers, and bills. It helps less when finance runs a dedicated ledger with multi-entity consolidation, in which case the honest advice is to invoice in Doitify only if the export path to your accountant is clean.

Conclusion

Project management software with invoicing is worth paying for when it removes the re-keying between timesheet, invoice, and ledger. The tool that does that best is the one whose billing model matches yours: hourly for Paymo, retainer and budget for Teamwork, tax-heavy agency work for Productive, quote-to-cash for Scoro, recurring service revenue for Accelo.

Check three things before you buy: the tier that actually includes invoicing, the minimum seats attached to that tier, and what the tool does with tax and currency. Those three decide your real cost far more than the headline price per seat.
