DeepLedger vs Numbers Game: MCP for Firms Compared

Numbers Game and DeepLedger solve the same problem in similar ways. Both are hosted MCP services built for accounting firms: one connector lets an AI app work across many QuickBooks Online and Xero client books, with access set per company, a log of what the AI did, pricing per connection rather than per seat, and a 14-day free trial. They differ in how writes are reviewed, which AI apps and other systems they reach, and what surrounds the work.

"Numbers Game" here means the product at numbersgame.xyz, which its own site writes as NumbersGame. It is run by NumbersGame B.V., a Dutch company, and its site says it began as an internal tool at AG Accounting, a firm run by the same founder, Anelya Grant.

We build DeepLedger, so read this with that in mind. Every statement about Numbers Game comes from its own public pages and press releases as of November 9, 2026, linked at the end. Where its pages do not say something, we say so rather than guess.

Who each one is for

Numbers Game is for accounting firms, solo accountants and fractional CFOs, according to its home page. It describes itself as an MCP tool provider: the firm brings its own Claude or ChatGPT account, and Numbers Game provides the accounting tools and context. Its home page leads with closing every client's books and delivering advisory work, and with auditing inherited books before a CFO builds a forecast.

DeepLedger is the accounting harness for AI. It is for accounting firms, small businesses and in-house finance teams that want their own people to do the books through the AI apps they already use, across many companies, with firm and client rules, skills, review tasks, access controls per company and an audit history built in.

Key differences

1. How writes are reviewed

Numbers Game is built around approving writes. Its home page says every write operation is proposed first and nothing reaches the books until you confirm it, its security page says bulk changes are split into a preview and a separate apply step, and its Stripe page adds that a proposal goes stale, and is refused, if the Stripe activity behind it changes before booking. The one place it describes automation is its direct bank and card feeds: a new connection starts at propose-only, and a firm can set rules and a confidence threshold that let routine items through, with exceptions held for review. Its pages are also open that the approval prompts belong to the AI app, whose always-allow setting stops them, and that a firm instruction can switch approval-before-write off. If your firm wants a person to approve each AI write before it reaches a client ledger, Numbers Game's workflow is designed around that.

DeepLedger writes when someone on your team asks it to, and puts review around the work rather than in front of each call. Xero invoices, bills, credit notes and journals are saved as drafts by default. Every write must name its company, or DeepLedger refuses it and nothing is written. There is no delete tool for posted QuickBooks transactions. Questions the AI cannot answer go to Tasks instead of guesses, and the month-end close and bank reconciliations end with a person's sign-off. Audit history shows what the AI did in each company. DeepLedger acts only when someone on your team asks: nothing runs on its own.

2. AI apps and ways in

Numbers Game is built around Claude. Its home page describes each client company as a Claude Project, it is listed in the Claude directory, and its FAQ says it also works with ChatGPT. Its roles page mentions other MCP clients too, but its pages name only Claude and ChatGPT, and one guide says Gemini does not work with it.

DeepLedger is one address, https://mcp.deepledger.ai/mcp, that you add to the AI apps your team already uses: Claude, ChatGPT, Cursor, Grok, Microsoft Copilot through Copilot Studio, or any app that can add a remote MCP server. You can also build your own agents with a DeepLedger API key. If people in your firm use different AI apps, check that each one is supported before you commit.

3. Systems beyond the ledger

Numbers Game reaches further into banking and payments. It can connect bank accounts and credit cards directly through Plaid for banks in the US and Canada, and it lists Stripe, Square, Ramp and Shopify connections; its security page says the Ramp and Shopify connectors are read-only. Its Stripe connector prepares period summaries, payout bookings and revenue-recognition journals for review before they are booked. It can also post weekly reviews and month-end close reports to a client's Slack channel, and produce branded PDF reports.

DeepLedger connects QuickBooks Online and Xero (beta), plus Bill.com with your own BILL credentials, where the AI can read, draft and edit bills, invoices, vendors and customers but never pays, approves or sends anything. Stripe is read for reporting, such as payouts, charges, refunds and disputes, and DeepLedger never changes anything in Stripe. QuickBooks companies can also connect a live bank feed, with AI category suggestions for you to approve. DeepLedger does not post to Slack or produce branded PDF deliverables.

4. Firm rules, skills and review

Both let a firm give the AI its own way of working. Numbers Game ships roughly three dozen readable SOPs, with a firm instruction section that takes precedence over them and is versioned and reversible. It also supports up to eight Markdown reference files with the firm's workflows, terminology and review thresholds, and a file of per-client rules, close instructions and vendor mappings, generated in its portal, for each client's Claude Project. Its pages also describe close checklists, reconciliation reports and bulk classification.

DeepLedger keeps that knowledge in two places your team can see and edit: the firm AI Brain, for operating procedures and accounting policies that apply to every client, and an AI Brain per company for that client's rules, such as "this supplier is always cost of sales". Skills show the AI how common jobs are done, including the month-end close, bank reconciliation, recording transactions and chasing invoices, and each company gets its own copy to adapt. Tasks keep questions and approvals in one list per company.

5. Data and security

Numbers Game's pages say QuickBooks Online and Xero data is read live and not stored, and that it keeps connection and access records, audit activity, reports and statement rows you choose to save or import, the bank and commerce data its bank, card and payment workflows need, and a record of what its Stripe connector booked. Its security page says it does not hold SOC 2 or ISO 27001 certification and describes an independent penetration test in October 2026.

DeepLedger works through the QuickBooks, Xero and Bill.com APIs and Stripe's official MCP, and keeps the records that make review possible: Tasks, AI Brain notes, close records and Audit history, plus some cached ledger data. Our security page lists our providers and practices. For either vendor, ask for current security documents before you connect client books.

Pricing as published

Numbers Game, as of November 2026 (from its home page):

Single: $59 a month, 1 connection credit.
Starter: $149 a month, 3 connection credits.
Growth: $299 a month, 7 connection credits; more at $40 a month each.
Scale: $549 a month, 15 connection credits; more at $35 a month each, with a dedicated implementation partner.
Enterprise: contract pricing, with no published price.

Every plan includes every capability, unlimited team seats and a 14-day free trial. One QuickBooks Online or Xero company uses 1 credit; each Stripe, Square or Ramp connection, bank institution or credit-card issuer uses half a credit. Numbers Game says it adds no per-token charge: you use your own Claude or ChatGPT subscription.

DeepLedger: $20 per connection per month for QuickBooks Online, Xero (beta) or Bill.com, and $10 per connection per month for Stripe, with unlimited users, a 14-day free trial and no card. A connection is one app for one company, connected once and used by everyone with access to that company. You use it with your own AI app subscription. See the pricing page.

A worked example: 10 client companies on QuickBooks Online or Xero (our arithmetic from each published price, before taxes):

Numbers Game: Growth at $299 for 7 credits, plus 3 credits at $40 = $419 a month.
DeepLedger: 10 × $20 = $200 a month.

The same 10 companies, 4 of them with Stripe:

Numbers Game: 12 credits, so Growth plus 5 credits at $40 = $499 a month.
DeepLedger: $200 + 4 × $10 = $240 a month.

The two prices buy different things. Numbers Game's credits also cover its direct bank and card connections, Square and Ramp, and its plans include the Slack summaries and branded PDF reports. Compare them against the work you need done, not only the number.

When to choose Numbers Game

Numbers Game is likely the better fit when:

your firm wants a person to approve each AI write before it reaches the books;
your team works in Claude, with a Claude Project per client;
you want weekly and month-end summaries posted to client Slack channels, or branded PDF reports;
you want bank and card accounts connected directly in the US or Canada, or Square, Ramp or Shopify alongside the ledger.

When to choose DeepLedger

DeepLedger is likely the better fit when:

your people use different AI apps and want published setup for each, such as Claude, ChatGPT, Cursor, Grok or Copilot, or you build your own agents;
you want firm-wide policies and each client's rules in an AI Brain your team can edit, with skills for the close and other recurring jobs;
you need a Tasks list for questions and approvals, close sign-off and an audit history per company;
your clients use Bill.com, or you want pricing per connection for each app rather than plans of credits.

Frequently asked questions

What is Numbers Game?

Numbers Game (written NumbersGame on its site) is an MCP tool provider for accounting firms, run by NumbersGame B.V., a Dutch company. It connects a firm's Claude or ChatGPT account to the QuickBooks Online and Xero client books the firm approves. Its site says it began as an internal tool at AG Accounting, a firm run by the same founder, Anelya Grant.

What is the main difference between Numbers Game and DeepLedger?

Both are hosted MCP services that let an AI app work across many QuickBooks Online and Xero companies, with access set per company and a log of what the AI did. Numbers Game is built around proposing each write for a person to approve before it reaches the books, and adds Slack summaries, branded PDF reports and direct bank connections. DeepLedger adds a firm and client AI Brain you edit in its portal, skills for jobs such as the month-end close, a Tasks list for review, Bill.com, and published setup for more named AI apps.

Which AI apps work with each?

Numbers Game's pages say it is built around Claude, where each client is a Claude Project, and that it also works with ChatGPT; its roles page also mentions other MCP clients. DeepLedger works in Claude, ChatGPT, Cursor, Grok, Microsoft Copilot (through Copilot Studio) and any app that can add a remote MCP server, and in agents you build with an API key.

How much do Numbers Game and DeepLedger cost?

As of November 2026, Numbers Game's plans are $59 a month for 1 connection credit, $149 for 3, $299 for 7 and $549 for 15, with Enterprise on contract and a 14-day free trial. A QuickBooks Online or Xero company uses 1 credit, and each Stripe, Square or Ramp connection, bank institution or credit-card issuer uses half a credit. DeepLedger is $20 a month per QuickBooks Online, Xero or Bill.com connection and $10 per Stripe connection, with unlimited users and a 14-day free trial with no card.

Does either one write to the books without a person?

Numbers Game says every write is proposed first and nothing posts until you approve it; its own pages add that an AI app's always-allow setting, or a firm instruction, can switch those approval prompts off. DeepLedger writes when someone on your team asks it to: Xero invoices, bills and journals are saved as drafts by default, questions go to Tasks instead of guesses, and the close and bank reconciliations end with a person's sign-off. Numbers Game also lets a firm set rules and a confidence threshold that automate routine work on direct bank and card feeds, starting at propose-only; DeepLedger acts only when someone asks.

Which is better for an accounting firm?

It depends on how your firm works. Numbers Game suits a Claude-first firm that wants a propose-then-approve workflow for writes, Slack drops and branded PDF deliverables. DeepLedger suits a firm whose people use several AI apps and want firm-wide rules, skills, review tasks and an audit record across QuickBooks Online, Xero, Bill.com and Stripe.
