QuickBooks closes your Carrollton books in English. Your entities, margins, and franchise tax do not fit its boxes.

Expect $45,000 to $110,000 depending on multi-entity consolidation, margin logic, and integrations. A multi-entity ledger with bilingual documents starts near $45,000 and ships in four to five months.

Because QuickBooks handles one entity cleanly but not the consolidation, bilingual documents, and landed-cost margins a Carrollton wholesaler needs. So the real accounting migrates to a spreadsheet, which a custom system replaces.

Yes. Multi-entity consolidation is built in, so two or three related companies roll up automatically instead of being stitched together by hand in a spreadsheet each period.

Yes. Reporting maps from your ledger to the Texas franchise (margin) tax return and the roughly 8.25% sales-and-use rate, so preparing your filing with the Comptroller is a report, not an annual manual rebuild.

Yes. The system generates invoices, statements, and vendor documents in Korean and English natively, so your bilingual customers and suppliers receive paperwork they can read.

Yes. Margin reporting is based on landed cost and consignment rather than list price, so you see true profitability by product and account instead of a headline number that hides freight and duty.

Four to seven months for most Carrollton businesses, longer with heavy inventory and payroll integration. Financial logic is validated carefully, which is why testing takes real time.

Yes. On a custom build you own the ledger data and the source code, with documentation, so your sensitive financials stay under your control rather than inside a vendor platform.

If you are a single entity with simple English-only books, QuickBooks or Xero is the right call. Build custom when multi-entity consolidation, bilingual documents, and landed-cost margins are pushing your real accounting into a spreadsheet.

Use a staged migration: export full history through the QuickBooks API or backup files, load it into the new system, then run both systems in parallel for at least one full closing cycle before cutting over. Expect cleanup work, because books older than three years almost always contain miscategorized transactions that surface during import. Digital Heroes schedules migration as its own project phase with its own sign-off, never as a launch-week task.

Three to five for a typical focused build: a project lead, one or two engineers, a designer, and part-time QA, which is the standard shape across 2,000+ Digital Heroes projects. Larger platforms justify 6 to 10, but a ten-person team on a small first version usually signals bill padding rather than horsepower. What predicts success is whether a senior engineer is writing your code daily, not the headcount on the proposal.

A skilled freelancer is the right call for a single-discipline scope under roughly $15,000, like a website, a plugin, or one integration. Above that, projects need design, backend, testing, and project management at once, and a solo builder becomes the single point of failure: if they get sick or take a bigger client, your project simply stops. Agencies bill 20-40% more per hour but carry continuity, code review, and someone to escalate to, which is what you are actually buying.

Yes, and it should be treated as standard scope rather than an add-on. Bank feeds typically come through aggregators like Plaid, payments through Stripe or your existing processor's API, and payroll providers such as Gusto and ADP publish APIs for pulling journal entries. The real constraint is smaller regional banks without feed coverage, which is worth verifying during scoping instead of discovering after launch.

You should, completely, through a written intellectual property assignment that transfers everything on final payment; without that clause, copyright stays with whoever wrote the code by default. Insist that the repository lives in your own GitHub organization from day one and that hosting, domains, and third-party accounts are registered to you. Also check for licenses to the agency's proprietary frameworks buried in the contract, because those can make switching vendors practically impossible even when you own your own code.

You should, outright, and the contract must say so with an explicit IP assignment clause rather than a usage license. Insist that the code lives in a repository you control from day one, so nothing, including the ledger schema and migration scripts, can be held back at the final invoice. Third-party libraries and any framework the agency reuses stay under their own licenses, and a clean contract lists exactly which those are.

Yes, and it is often the right first step. QuickBooks Online has a public API, so an agency can build a custom layer for quoting, inventory, or field service that pushes clean transactions into QuickBooks, which stays your ledger of record. Roughly half of the accounting engagements Digital Heroes scopes start this way because it costs a fraction of a full build and leaves your accountant's workflow untouched.

Neither is secure by default; security tracks the practices of whoever builds and operates the system, not the model. SaaS gives you the vendor's certifications and patching but puts your data in a shared multi-tenant platform on their terms, while custom gives you full control over data residency, access rules, and compliance requirements like HIPAA, with the responsibility sitting with you and your agency. Before hiring anyone for a system holding sensitive data, ask for their security checklist: encryption at rest and in transit, an OWASP Top 10 review, role-based access, and a penetration test before launch.

Xero stays cheaper as long as its workflows fit your business, since even its top plan costs around $1,000 a year and custom development starts around $25,000. The math flips once you stack add-ons: companies Digital Heroes scopes after they have bolted inventory, job costing, and approval apps onto Xero are usually paying more for the app stack and the labor of keeping five tools in sync than for Xero itself. Custom wins when the real cost is that labor and its errors, not the license fee.

At minimum: encryption at rest and in transit, role-based access control, and immutable audit logs recording every change to the ledger. If outside parties rely on your numbers you will want SOC 2 style controls, and storing card data pulls you into PCI DSS, which most builds avoid by tokenizing payments through Stripe or a similar processor. Your industry adds its own rules, so compliance requirements belong in the written spec, not in a post-launch retrofit.

Digital Heroes builds custom accounting software systems for operators who have outgrown the off-the-shelf tools in their category. The work is delivered remotely: our engineers work from Delhi and Lucknow, leadership is in New York, and some team members live in London and Sydney and work remotely from there. We have no office in Carrollton. You can chat with the team directly, and every form gets an email reply within 24 hours.
