Your Seattle HR Stack Cannot Handle Equity, and Spreadsheets Are Filling the Gap: problems and solutions
When BambooHR, Workday, or Gusto cannot model your equity refreshes, your aerospace compliance training, or your specific comp bands, a custom HR (Human Resources) layer is justified. A focused build runs $60,000 to $150,000 over 4 to 7 months. Most Seattle companies should keep their HRIS for payroll and benefits and build only the layer it does poorly, which is usually equity, performance, and the compliance training your industry mandates.
Businesses in Seattle run into very specific operational problems. Across cloud and software, aerospace, e-commerce, the same Funded startups and mid-size product teams burn cash on bloated cloud bills and tangled microservices that nobody fully owns, making it hard to ship features without breaking something else. keeps surfacing, manual workflows that do not scale, disconnected tools that leak data, and software that fights the team instead of helping it. The right custom build closes those gaps directly, turning the daily friction Seattle companies feel into systems that just work, so the team spends time on customers instead of workarounds.
Your HRIS runs payroll and PTO fine. Everything else lives in spreadsheets. Equity grants, refresh schedules, and vesting are tracked in a cap-table tool that does not talk to comp reviews. Aerospace compliance and safety training certifications are in another sheet. Performance reviews happen in a third tool that does not connect to comp at all. Every comp cycle is a manual reconciliation across four systems that never agree.
BambooHR, Workday, Gusto, and ADP are built for standard employment. Seattle tech comp is not standard. Equity is a first-class part of the offer, refreshes and accelerations are common, and a cloud company's comp philosophy does not fit a generic comp module. An aerospace employer adds mandatory recurring certifications and training records that auditors check. The HRIS handles the boring 80% well and leaves the 20% that actually matters in spreadsheets.
The case for owning your hr
A custom HR layer is worth building when total compensation, including equity, is central to your offer and no off-the-shelf module models it. For a Seattle tech or aerospace employer, that means an equity-aware comp and performance layer, or a compliance-training tracker, that sits on top of your existing HRIS and finally gives one accurate view of total comp and certification status.

Delivery, week by week
Exactly what you get
You get the HR layer your HRIS does badly, built to fit your actual comp. For a Seattle tech employer that is an equity-aware total-comp view where refreshes, vesting, and accelerations sit alongside cash, connected to performance so calibration runs on one dataset. For an aerospace employer it adds compliance and certification tracking with expiry alerts so audits become a query. Your existing HRIS keeps running payroll and benefits; the build only replaces the spreadsheets that were quietly doing the hard part.
How to choose a developer in Seattle
HR and comp data is among the most sensitive you hold, so security maturity is the first filter. Ask how a candidate would scope this system for SOC 2 and protect comp and PII. The second filter is comp fluency: have them explain how an equity refresh interacts with an existing vesting schedule, because if they fumble the vesting math they will erode employee trust the day the numbers look wrong. Favor a partner who insists on keeping your HRIS for payroll and building only the equity and compliance gap.
- Equity refreshes, vesting, and accelerations modeled alongside cash for a true total-comp view
- Compliance and safety certifications tracked in-system with expiry alerts, so audits stop being fire drills
- Performance and comp connected, so calibration uses one dataset instead of a four-system reconciliation
- Comp bands and philosophy that match your actual model rather than a generic module's assumptions
- A single source of truth that ends the spreadsheet sprawl HR currently maintains by hand
- HR data is highly sensitive, so you take on serious security and privacy obligations the vendor used to own
- You still need the HRIS for payroll and benefits, so this is an addition to maintain, not a replacement
- Comp and equity logic is intricate, and getting vesting math wrong erodes employee trust fast
- If your comp is genuinely simple, this build solves a problem you do not really have
- !No experience with equity or vesting math. Ask them to explain how a refresh grant interacts with an existing vest schedule
- !Weak on data security. Ask how they protect comp and PII and support a SOC 2 scope
- !They want to replace your whole HRIS. Ask why you would not keep it for payroll and build only the gap
- !No audit logging. Ask how a comp change six months ago can be traced to who made it
- !They ignore compliance certifications. Ask how aerospace training records and expiries are handled
Most Seattle teams pricing hr end up comparing notes on pos, warehouse management, helpdesk & ticketing too; the systems share one data spine.

Frequently asked questions
Should we replace BambooHR or build on top of it?
Build on top. BambooHR and similar tools handle payroll, PTO, and benefits well. The value is in adding the equity, performance, and compliance layer they do poorly, integrated via API, not in replacing a working HRIS.
Can custom software handle equity refreshes and accelerations correctly?
Yes, that is precisely where off-the-shelf comp modules fall short. A custom layer models refreshes, vesting schedules, and accelerations explicitly, giving a true total-comp picture standard tools cannot produce.
How do we keep sensitive comp data secure?
Through role-based access, encryption, and thorough audit logging from day one, designed to fit into a SOC 2 scope. HR data demands this rigor, which is why security maturity is the top criterion when choosing a builder.
