Your Seattle HR Stack Cannot Handle Equity, and Spreadsheets Are Filling the Gap
When BambooHR, Workday, or Gusto cannot model your equity refreshes, your aerospace compliance training, or your specific comp bands, a custom HR layer is justified. A focused build runs $60,000 to $150,000 over 4 to 7 months.

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.
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

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.
What about aerospace compliance training records?
A compliance module tracks certifications, recurring training, and expiries with alerts, so an auditor request becomes a query instead of a spreadsheet scramble. This is a common Seattle aerospace requirement standard HRIS tools handle weakly.
Is this worth it if our equity program is small?
Probably not yet. If comp is mostly salary and bonus with minimal equity, BambooHR or Gusto likely suffices. Build when equity complexity or compliance tracking has genuinely outgrown spreadsheets.
How much does custom HR software cost for a small business?
A core HR system covering employee records, onboarding, time off, and documents typically lands between $30,000 and $80,000 for a small business, based on Digital Heroes delivery across 2,000+ projects. Full platforms that add applicant tracking, performance reviews, and time and attendance run $80,000 to $250,000. Most teams under 100 employees start with the core and expand after the first release proves itself.
Can we keep using BambooHR while the custom system is being built?
Yes, and you should; the standard approach is to run both in parallel and cut over one module at a time, using BambooHR's API to keep employee data in sync. Your HR team keeps working normally while each new module is tested against real records. The final cutover then retires a system you have already replaced in daily use, not one you are gambling on.
What does it cost to maintain custom HR software after launch?
Plan for 15 to 20 percent of the original build cost per year, the average across Digital Heroes maintenance contracts, covering security patches, dependency updates, small feature changes, and monitoring. Hosting for a company under 1,000 employees usually adds $100 to $400 a month on AWS or similar. Unlike BambooHR or Workday, the cost does not grow every time you hire ten more people.
What happens to our HR system if the development agency shuts down?
Nothing, if the handover was done right: you hold the repository, the cloud accounts, the deployment runbook, and the schema documentation, so any competent team can take over maintenance. This is why code ownership and infrastructure access belong in the contract rather than in goodwill. Ask for the handover package as a deliverable of the first release, not something promised for later.
Is Workday realistic for a company under 500 employees?
Usually not; companies that bring Digital Heroes their Workday quotes have been looking at six-figure implementations with 6 to 12 month rollouts before any customization starts. A custom HR platform scoped to what a 200-person company actually uses typically costs less than that implementation alone. Under 500 employees you would be paying for enterprise depth you will not touch for years.
Should I hire a freelancer or an agency to build our HR system?
A freelancer works for a single module or one integration, but a full HR platform needs design, backend, security review, and QA running at once, which is agency territory. Senior freelancers in Seattle usually quote $80 to $150 an hour, and everything stops when they take a vacation or a bigger contract. For software holding every employee's salary and personal data, a bus factor of one person is the real cost.
When does Gusto's per-person pricing stop making sense?
Gusto's Plus plan lists at $80 per month plus $12 per person, so a 250-employee company pays roughly $37,000 a year for workflows it cannot change. The common fix is keeping Gusto for payroll, which it does well, and building custom software for onboarding, scheduling, and PTO around it through Gusto's API. That caps the subscription at payroll only while the workflows finally match how you operate.
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.
Will custom HR software scale from 100 to 1,000 employees?
Yes, comfortably. A thousand employee records is a tiny dataset by database standards, so the real scaling work is organizational: multi-state tax setups, layered approval chains, and role hierarchies. A properly designed system absorbs those through configuration instead of code changes. This is where custom beats off-the-shelf, because you add complexity as you actually acquire it rather than paying for an enterprise tier up front.
Does it matter which tech stack the agency wants to use?
Yes, but not in the way most buyers expect: the goal is boring, popular technology such as React, Node.js or Python, and PostgreSQL, because any future team can maintain it and hiring a replacement developer takes days, not months. The red flag is an agency-proprietary framework or an unusual language, which welds you to that one vendor no matter what your contract says about code ownership. A useful test: could you find three freelancers fluent in this stack within a week? If not, push back.
Can we migrate years of data out of our current system into new custom software?
Almost always yes, through CSV exports or the vendor's API, and migration should be scoped as its own workstream with field mapping, a dry run, and a planned cutover window rather than an afterthought. The real time sink is rarely moving the data; it is cleaning it, since years of duplicates, free-text fields, and inconsistent formats surface all at once. Pull a full export from your current vendor before committing to anything new, because some SaaS plans restrict exports on lower tiers.
Who can build custom HR software for a business in Seattle?
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 Seattle. You can chat with the team directly, and every form gets an email reply within 24 hours.
