Your San Francisco startup's comp is mostly equity, and BambooHR has no idea what to do with it
Custom HR software for a San Francisco tech company runs $70k to $190k and takes 4 to 8 months. You build instead of buying BambooHR or Workday when equity-heavy compensation, complex visa and immigration tracking, or rapid org changes break off-the-shelf HR tools.

Custom HR (Human Resources) software for a San Francisco tech company runs $70k to $190k and takes 4 to 8 months. You build instead of buying BambooHR or Workday when equity-heavy compensation, complex visa and immigration tracking, or rapid org changes break off-the-shelf HR tools. Most San Francisco startups should run Gusto or BambooHR until equity, immigration, or scale make the gaps a real liability, then build the layer that off-the-shelf systems can't model.
Compensation at your San Francisco startup is mostly equity, and that's where the off-the-shelf HR stack falls apart. BambooHR and Gusto track salary cleanly but treat option grants, vesting schedules, refresh grants, and 409A-driven repricing as fields someone updates by hand, if at all. Meanwhile a third of your engineers are on visas, so you're tracking H-1B timelines, green card stages, and travel restrictions in a spreadsheet that an HR person prays they keep current. The system of record for your most valuable and most sensitive employee data is duct tape.
BambooHR, Workday, Gusto, and ADP are built for companies whose compensation is salary plus a bonus and whose workforce is mostly domestic. A San Francisco tech or biotech company is neither. Equity is the core of your offer and your retention story, immigration is a constant operational reality, and your org chart changes monthly as you reorg around new bets. The generic HR tools handle the commodity, payroll, PTO, onboarding checklists, but the parts that actually define working at a venture-backed San Francisco company are exactly the parts they can't model.
- Equity is the core of comp and your HR tool tracks it by hand or not at all
- A meaningful share of your team is on visas and immigration lives in a spreadsheet
- Frequent reorgs keep breaking your org chart and reporting lines
- Equity confusion or visa lapses have become real retention or legal risks
- Your comp is mostly salary and bonus with little equity complexity
- Your workforce is mostly domestic with minimal immigration tracking
- You're small enough that Gusto or BambooHR covers the whole need
- You lack the security maturity to safely own sensitive HR data
- Equity modeled properly: grants, vesting, refreshes, and repricing tracked as real data employees can actually see
- An immigration tracker that turns visa and green-card timelines into managed deadlines, not a fragile spreadsheet
- An org chart and reporting model that survives monthly reorgs instead of breaking on every change
- Self-serve equity clarity for employees, so retention conversations start from value, not confusion
- Accurate comp and headcount data for leadership and the board through constant organizational change
- Payroll, tax, and benefits compliance are genuinely hard and Gusto or ADP already do them well, keep buying those
- HR data is highly sensitive, so a weak build creates a privacy and security liability worse than the spreadsheet
- Cap-table and equity logic overlap with tools like Carta, so you may integrate rather than rebuild that piece
- Custom HR software needs ongoing maintenance and careful access control that a small team must commit to

The features that matter for San Francisco
San Francisco HR: the full scope
The engagements San Francisco teams bring us most often: Workday integration, leave management, performance management software, custom HR software, HRIS development, payroll software and employee onboarding system.
Exactly what you get
An HR layer built for how a venture-backed San Francisco company actually compensates and staffs: equity grants, vesting, refreshes, and 409A repricing modeled as real data employees can see, an immigration tracker that turns visa timelines into managed deadlines, and an org chart that survives monthly reorgs. You keep buying payroll, tax, and benefits from Gusto or ADP and integrate them, rather than rebuilding solved compliance. You get role-based access and audit logging for sensitive data, plus headcount and comp reporting feeding the business intelligence dashboards your board reviews.
How to choose a developer in San Francisco
San Francisco HR data is among the most sensitive you own, so hire a team that leads with security and knows the domain. Ask how they'd model a refresh grant and a 409A reprice, and how they'd protect and audit employee records. The strong agencies integrate payroll and cap-table tools rather than rebuilding them, and they treat immigration tracking as a real compliance problem; the weak ones hand-wave both. Insist on a paid discovery, a clear data-security plan, and a reference from a startup with equity-heavy comp and a visa-heavy team.
From kickoff to launch: the schedule
- !They want to rebuild payroll and tax; ask why you'd leave Gusto or ADP's compliance
- !No questions about your equity model; ask how they'd track vesting and 409A repricing
- !They gloss over data security; ask how they'd protect and audit sensitive HR records
- !No plan for cap-table integration; ask whether they'd rebuild or connect to Carta
- !They've never built immigration tracking; ask for a reference with visa-heavy teams
Teams investing in HR in San Francisco usually scope it next to pos, warehouse management, helpdesk & ticketing, since these systems share data and budgets. Weighing options across the region?

Frequently asked questions
Should a San Francisco startup build custom HR software or use BambooHR?
Use BambooHR or Gusto until equity complexity, immigration tracking, or constant reorgs make the gaps a liability. The trigger is usually equity tracked by hand plus visa timelines in a spreadsheet, at which point a custom layer on top of bought payroll makes sense.
How much does custom HR software cost in San Francisco?
An equity-and-immigration tracking layer runs $70k to $110k. A full HR platform with org and reporting runs $130k to $190k over 6 to 8 months. A payroll and cap-table integration layer runs $45k to $85k.
Should custom HR software replace payroll like Gusto or ADP?
No. Payroll, tax, and benefits compliance are solved problems those vendors handle well, and rebuilding them is risk for no gain. The right build adds the equity, immigration, and org layers off-the-shelf tools lack, and integrates payroll rather than replacing it.
Can custom HR software track equity better than BambooHR?
Yes, that's usually the core reason to build. It models grants, vesting schedules, refresh grants, and 409A repricing as first-class data with employee-facing views, which off-the-shelf HR tools treat as static fields someone updates manually.
What should custom HR software integrate with?
Typically your payroll (Gusto or ADP), your cap-table tool such as Carta for equity, your data warehouse, and business intelligence dashboards so leadership and the board see accurate headcount and comp through reorgs.
Who owns the code if an agency builds our HR software?
You should own it outright, with the contract assigning full intellectual property to you on final payment and the code living in a repository you control from week one. Watch for agencies that license you their platform, because that recreates the vendor lock-in you left BambooHR to escape. Digital Heroes assigns 100 percent of custom code to the client; the only carve-outs should be standard open source libraries.
What integrations does a custom HR system actually need?
The standard set is single sign-on through Google Workspace or Microsoft 365, a payroll provider like ADP or Gusto, accounting via QuickBooks or Xero, and Slack or Teams for notifications; background check services like Checkr come up for hiring-heavy teams. Integrations take 15 to 25 percent of total budget in Digital Heroes HR builds, so list them during scoping. Each one you name upfront is a change order you avoid later.
What questions should I ask a development agency on the first call?
Ask who exactly will build it, what happens when scope changes mid-project, what their maintenance terms are after launch, and what they will need from you every week. Then ask them to describe a project that went wrong and what they changed afterward; teams that have shipped at real volume have war stories, and teams claiming a perfect record are hiding something. The scope-change answer matters most: a disciplined shop describes a written change-order process, not a vague promise to be flexible.
How many developers does it take to build an HR platform?
A typical Digital Heroes HR build runs 4 to 6 people: a project lead, a designer, two or three developers, and a QA engineer, with security review pulled in at milestones. A single module needs just two. Bigger teams rarely ship HR systems faster, because the bottleneck is decisions about workflows, not typing speed.
At what point does a company outgrow BambooHR?
The breaking point Digital Heroes sees most often is 100 to 250 employees, when approval chains, multi-state rules, or shift scheduling stop fitting BambooHR's fixed workflows and HR starts managing exceptions in spreadsheets. If your team exports to Excel every week to do something the platform cannot, you have already outgrown it. Per-employee pricing compounds the problem, since the bill grows with every hire while the feature gaps stay the same.
How long until custom HR software pays for itself?
For companies over 100 employees, payback typically lands in 24 to 36 months across Digital Heroes projects, driven by cancelled per-seat subscriptions and recovered HR admin hours. A 200-person company spending $40,000 a year on HR tools plus a day a week of manual workarounds crosses even faster. Under 50 employees the math usually favors staying on Gusto or BambooHR, and an honest agency will tell you that.
How do I calculate whether custom software will pay for itself?
Divide the build cost by the monthly benefit, where benefit is hours saved times loaded hourly cost, plus subscription fees replaced, plus any revenue the software unlocks. Three staff saving 10 hours a week each at a $40 loaded rate is about $62,000 a year, which pays back a $60,000 build in roughly 12 months. Across Digital Heroes internal-tool projects, 12 to 24 months is the normal payback range, and anything projecting under 6 months usually means the spreadsheet is hiding costs.
Why do agencies charge for a discovery phase instead of quoting for free?
Because an accurate quote requires real work: mapping your workflows, finding the edge cases, and writing a specification, which typically takes 1 to 3 weeks and costs $2,000 to $10,000 at Digital Heroes depending on system complexity. You leave discovery owning a written spec and a fixed price you can take to any vendor, so the money is not locked into one agency. Free estimates are guesses, and the guess usually becomes your budget overrun six months later.
What are the biggest mistakes first-time software buyers make?
Choosing the lowest bid, paying more than 30-40% upfront instead of on milestones, skipping a written specification, and having no maintenance plan for after launch. The most expensive of the four in Digital Heroes rescue projects is the missing spec: without written acceptance criteria, done becomes an argument instead of a checklist, and every disagreement resolves in the vendor's favor. Fix those four and you have avoided most of the ways these projects fail.
Does my development team need to be located in San Francisco?
No, most software projects run fully remote without any quality penalty, and what actually matters is 3 to 4 hours of working-hour overlap and a fixed weekly demo call. A team based in San Francisco earns its premium in specific cases: hardware installations, warehouse or clinic floor shadowing, and discovery workshops where watching your staff work beats any written brief. Choose for senior engineers and a track record first, and treat geography as a tiebreaker.
Who can build custom HR software for a business in San Francisco?
Digital Heroes builds custom HR 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 San Francisco. You can chat with the team directly, and every form gets an email reply within 24 hours.
