Your San Francisco startup's comp is mostly equity, and BambooHR has no idea what to do with it: for startups and scale-ups
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.
Fast-growing companies in San Francisco cannot afford software that breaks at the next stage of growth. Whether you are early in technology and AI, venture capital, fintech or already scaling, the goal is the same, ship quickly without piling up technical debt that slows the next hire and the next round. The right partner builds San Francisco startups a foundation that flexes as headcount, traffic, and revenue climb, so the product keeps pace with the ambition behind it.
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

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.
