Consulting Firm Software: Build or Buy for Time, Staffing and Margin?
Billable headcount decides this, and the line sits at roughly 40 consultants.

Billable headcount decides this, and the line sits at roughly 40 consultants. Below it, buy: Harvest plus Float costs a few hundred dollars a month, the monthly spreadsheet reconciliation genuinely does not hurt enough yet, and a build would automate a process that has not stabilised. Above 50 with real rate card complexity, the arithmetic flips hard. At 62 consultants billing $180 an hour at 70 percent utilisation, one point of realisation is roughly $162,000 a year, and a rate card engine that recovers a fraction of one point covers a first release.
When is off the shelf genuinely the right call here?
Stay on Harvest plus Float if you are under roughly 30 to 40 billable people, run mostly time and materials work on a simple rate card, and operate one legal entity in one currency. The tools cost a few hundred dollars a month, the reconciliation your finance lead does on the sixth business day is annoying rather than expensive, and the complexity a custom build absorbs does not yet exist in your business. The same answer applies to a firm of any size that runs one practice doing one shape of work.
Kantata and Deltek Vantagepoint are legitimate products solving a standardised version of this problem, and if your rate cards fit their model you get a working system faster than any build could deliver one. Buying is the right call there. Accept honestly what you are signing up for: an implementation plus licensing that scales with headcount, and a process that bends toward the product rather than the other way round. For plenty of firms that trade is sound.
There is a third buy case worth naming. If nobody in your firm will own the rate card data, do not build. A margin engine reporting against contracts nobody has entered is worse than no engine, because it is confidently wrong and partners will price the next three proposals on it. Someone has to enter new master service agreements and amendments promptly, forever. Where that person does not exist, a configured product used properly beats a custom platform used badly every time.
When does a custom build actually pay off?
Three of these together, and the case is made.
Your rate cards carry exception logic no tool can express. A rate card is a contractual object with role levels, effective date ranges, volume tiers, annual escalators, expense caps and subcontractor pass through markup. Off the shelf tools model a rate as a number on a person or a project, so when a partner discounts a senior manager from $325 to $290 in an email during scoping, that change lives in the email. Time keeps flowing at the old rate, you invoice at the new one, and the variance is written off at quarter close as a billing adjustment.
More than fifteen percent of delivery runs through subcontractors. Those people are not employees, their invoices arrive as attachments and get keyed into the ledger weeks later, and until then your engagement margin is wrong by whatever that number is. This is the single biggest source of hidden margin error at firms of this shape.
You operate more than one entity or currency, so a subsidiary billing a client in another country brings intercompany transfer pricing that has to net out.
Your resourcing manager is a single point of failure and everyone knows it, because the answer to who should staff this engagement depends on cost rate, skills, travel load and pipeline that no calendar tool holds.
Or you have already paid for a suite implementation and the firm quietly went back to the spreadsheet. That is the loudest signal in the category. It means the mismatch is between your operating model and the tool's assumptions, and a second vendor will not fix it.
How do they compare on the things that matter in this industry?
- Rate resolution. Packaged tools attach a rate to a person or a project. A contract is effective dated with tiers and exceptions, so the only correct design resolves a time entry against the contract at the moment of entry and re prices open work in progress when a rate changes. Everything downstream depends on this and nothing else compensates for getting it wrong.
- Staffing data. Float and Resource Guru answer whether a person is free, which is a calendar question. The real question involves cost rate, industry experience, certification expiry, trailing travel days and the margin impact of each choice. None of that is in a scheduling tool because a scheduling tool models capacity, not people.
- Timesheet signal. A form can send a reminder. It cannot propose an entry, because it has no idea what the consultant did. Calendar events, project channel activity and document edits are signal you already own, and using them turns Friday night reconstruction into same day confirmation.
- Trajectory versus consumption. Hours against a budget is a consumption view. Projected margin at completion computed from burn rate against a delivery plan is a trajectory view, and it is the difference between a change order conversation in week four and a write off in week twelve.
- Subcontractor economics. Cost rates, purchase order caps and pass through markup are not concepts a project tool holds, which is why the shadow spreadsheet exists.
- Per seat economics. Licensing scales with headcount indefinitely, which is efficient at 25 consultants and a growing line at 120.
What does total cost of ownership look like at your scale?
From Digital Heroes delivery experience, a contract and rate card engine with per engagement margin runs $60,000 to $95,000. A first release adding assisted time capture, an engagement plan with planned hours by role, projected margin at completion and a staffing screen that recalculates margin live runs $95,000 to $130,000 over twelve to sixteen weeks. A full platform adding subcontractor cost accrual with purchase order caps, revenue recognition, multi entity and multi currency, client time approval portals and pipeline integrated bench forecasting runs $150,000 to $400,000 across six to twelve months.
Three components drive the upper band. Revenue recognition under ASC 606 or IFRS 15 adds $30,000 to $60,000, and the difficulty sits in estimate revisions, change orders and contract modifications rather than the base percentage of completion calculation. Multi entity and multi currency adds $25,000 to $55,000. A deep two way integration with your enterprise resource planning (ERP) system adds $20,000 to $50,000, because reading actuals is cheap and writing work in progress, unbilled revenue and period close entries is not.
Running cost is modest for a system of this shape. Support and iteration is 15 to 18 percent of build cost a year, hosting is $3,000 to $8,000, and integration maintenance is $4,000 to $10,000 as accounting and customer relationship management (CRM) vendors revise their interfaces. On a $128,000 first release that totals roughly $26,000 to $36,000 a year.
Set that against your own arithmetic rather than ours. Sixty two consultants at 70 percent utilisation of a 2,080 hour year is about 90,000 billable hours. At $180 that is roughly $16.2 million of billing, so one point of realisation is around $162,000 annually. Separately, a consultant at a $140 loaded cost rate sitting on the bench costs about $5,600 a week.
What does the hybrid look like, and when is it the honest answer?
In this category the hybrid is not a fallback, it is the design. Do not rebuild the general ledger, the customer relationship system or human resources (HR). Build the contract to time to margin chain, which is specific to how your firm makes money, and let it push clean data into everything you already own.
That boundary is unusually clean. Your accounting platform is good at being a ledger and has no opinion about escalators or volume tiers. Your customer relationship system holds weighted pipeline that feeds bench forecasting and knows nothing about cost rates. Neither vendor will ever model your rate exceptions, because those exceptions are yours alone.
There is a sequencing decision inside the hybrid that saves real money. Report margin before you recognise revenue. Live engagement economics changes partner behaviour in week four of an engagement, which is where the money is. Recognition changes your close, which matters to your auditors rather than to your margin. Sequence them in that order and the first release pays for itself before the second phase starts.
The smallest useful version is the rate card engine plus per engagement margin, with time still captured in Harvest and staffing still planned in Float. It is the cheapest item in the band and it kills the workbook, which is the thing everyone actually hates. Add assisted time capture second, because trustworthy input is what makes every downstream number worth reading. Leave client portals and recognition until you have a full billing cycle of evidence.
Which should you choose, by operator size and stage?
Under 30 billable consultants, one entity, simple rate card: buy. Harvest plus Float, and spend the difference on a finance hire who will pay for themselves faster than any software.
Thirty to fifty consultants: buy, then measure two numbers for a quarter. How many hours a month your finance lead spends answering whether one engagement made money, and how many weeks after the fact your realisation leakage surfaces. If leakage surfaces six weeks late, your last three proposals were priced on figures that were already wrong, and that is the cost you are trying to size.
Above fifty consultants with real rate complexity: build the rate and margin engine and integrate around it. This is the population where the workbook has become load bearing and a single person is the source of truth for how you get paid.
Firms above fifteen percent subcontracted delivery: build earlier than headcount suggests, and put subcontractors into the same time entry system with cost rates and purchase order caps attached. Blocking entry past the cap, rather than warning about it, is what makes the number true.
Multi entity firms and anyone who has already implemented a suite and returned to the spreadsheet: build. In the second case the evaluation is finished, you simply have not called it yet.
If you would rather scope this before committing budget, Digital Heroes contracts through India LLP, US LLC and UK LTD entities, so the agreement and the intellectual property assignment sit under law your own advisers already read. Nothing about that commits you to the build.

Frequently asked questions
How hard is it to leave Harvest and Float once we have built our own layer?
Time entries import cleanly from the Harvest interface, so historic hours are not the problem. The hard part is reconstructing rate history, because rate cards mostly live in emails and signed agreements rather than in the tool.
Budget two to three weeks of a finance analyst's time to validate rate history, or run document extraction over the master service agreements and have them approve the drafts. Plan one full billing cycle in parallel, typically thirty to forty five days, so finance can reconcile new invoices against old before you switch anything off.
What happens if Kantata or Deltek changes our licensing terms?
Both price against headcount, which means the line grows as the firm grows regardless of any repricing. Model it against your projected consultant count three years out rather than today's, because that projection is what actually changes the decision.
A build does not remove every subscription, since your accounting platform, identity provider and signature tooling all continue. What changes is that your rate logic, engagement economics and margin history sit in something you own, so a repricing becomes a commercial conversation rather than a migration you cannot afford to run.
How long does a first release take, and when can we trust the numbers?
Twelve to sixteen weeks to build, then one full billing cycle in parallel before anyone relies on it. Trust arrives at a specific moment, and it is worth naming in your acceptance criteria: insist the rate card engine is accepted by re pricing three real historical engagements and matching what was actually invoiced.
Firms that skip that test spend the first two months after launch arguing about whether the system or the spreadsheet is right, which is the state they were paying to leave.
Is a build cheaper than Kantata over three years?
Not in year one, and anyone claiming otherwise is discounting the implementation you would still be doing either way. Kantata is a mature product and if your rate cards fit its model you reach value faster.
The comparison shifts across three years, because its pricing scales with headcount while a build's ongoing cost is support plus hosting. The clearest signal is having already implemented one of these products and watched the firm quietly return to the spreadsheet, which means the mismatch is with your operating model rather than the vendor.
What does ASC 606 revenue recognition add, and should it be in the first release?
Roughly $30,000 to $60,000, and no. Percentage of completion requires linking estimated total effort, actual effort and contract value in one place, and the intricacy sits in estimate revisions, change orders and contract modifications, each of which restates prior periods and has to explain why.
Sequence it after live margin reporting. Have your audit firm review the logic before it goes live rather than discovering a disagreement during your first close on the new system, which is an expensive quarter to have.
Can we fix timesheet compliance without building anything?
Not meaningfully. A reminder email is the entire intervention a form can offer, and consultants will keep filling Friday at 6pm from memory in four hour blocks against whichever code they remember.
What works is proposing entries rather than requesting them. Pull calendar events, project channel activity and document edits, present a pre filled draft the consultant accepts or corrects on their phone in under two minutes. Firms that do this move from Friday night reconstruction to same day confirmation, which is what makes every downstream utilisation and margin figure worth reading.
What does it cost to run each year, and what gets forgotten?
Budget 15 to 18 percent of build cost annually for support, $3,000 to $8,000 for hosting and $4,000 to $10,000 for integration maintenance. On a $128,000 first release that is roughly $26,000 to $36,000 a year.
Two internal costs get forgotten. Someone has to curate rate cards, entering new agreements and amendments promptly, because a quarter of neglect turns a margin engine into a confident source of stale numbers. And if you build recognition, your auditors will want to understand it every year, which is partner and controller time plus documentation you should have written during the build.
Who owns the code if an agency builds our margin engine?
You should own it outright: full source, repository access in your own organisation from the first commit, infrastructure accounts in your name and no licence back clause. Confirm it in the contract before kickoff rather than at handoff.
At Digital Heroes the client owns the code from the first commit. Any arrangement where the agency retains intellectual property or hosts on its own accounts creates a hostage situation the day you want to change vendors, and in a system holding your contract economics that is a worse dependency than the subscription you left.
What does it cost to keep custom software running after launch?
Budget 15-20% of the original build cost per year, which on a $100,000 system means $15,000 to $20,000 for security patches, dependency updates, bug fixes, and small improvements as real usage reveals what the spec missed. Cloud hosting for a typical business application adds $50 to $300 a month on top. Skipping maintenance does not save the money; in Digital Heroes rescue work, unmaintained systems typically need a far more expensive rebuild within about three years.
What should the first version of a custom project management tool include, and what should wait?
Version one is the painful workflow plus the basics: tasks, projects, permissions, and one integration, shippable in 12 to 16 weeks. Everything that feels essential but is not should wait: Gantt views, custom report builders, native mobile apps, and public API access all belong in version two, once real usage shows what matters. Teams that run the MVP for a quarter before expanding consistently spend less and drop features that looked critical on paper.
Should I customize Jira with plugins or just build our own tool?
If two or three Marketplace apps close the gap, stay on Jira, since it starts around $8 per user per month and the apps ride on top. The trap is that cloud apps are licensed for every user on the instance, so in Digital Heroes audits a 200-seat Jira with three or four paid apps plus a ScriptRunner consultant often lands at $30,000 to $50,000 a year. At that run rate a custom tool scoped to your actual workflow pays for itself in two to three years and ends the plugin upgrade treadmill.
What happens to my software if the agency shuts down or we stop working together?
Nothing dramatic, if the engagement was set up correctly: the code sits in your repository, hosting runs on your cloud account, and a handover document explains how to deploy and operate the system. Any competent replacement team can then take over in days rather than months. If the agency controls the repo, the servers, or the domain, fix that now, because renegotiating access during a dispute is the most expensive place to discover the problem.
I run a 15-person business. Is there a cheaper option than a full custom project management build?
Yes: a custom layer on top of a tool you already pay for. Digital Heroes ships client dashboards, automated reporting, and workflow glue built on the Asana and ClickUp APIs for $8,000 to $20,000, which fixes the specific gap without replacing the whole tool. A full custom platform rarely makes sense below roughly 50 seats unless the software faces your own customers.
Can a solo freelancer build project management software, or do I need an agency?
A strong freelancer can deliver a single-team internal tracker in the $15,000 to $25,000 range. Once you need role-based permissions, real-time updates, several integrations, and someone on call after launch, you need a 4 to 5 person team, because those features cross design, backend, and QA at once. The bigger freelancer risk is continuity: one person on vacation becomes an outage in your delivery pipeline.
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.
Who can build a custom project management software system?
Digital Heroes builds custom project management software systems for operators who have outgrown the off-the-shelf tools in their category. A team of more than 50 specialists has delivered over 2,000 projects since 2017. Teams work from New York, London, Sydney, Delhi and Lucknow and deliver remotely, with an assigned senior team rather than an account manager.
Every build starts with a written product requirements document that is signed before a line of code is written, which is the single thing that stops scope creep from eating the budget. Scoping runs about a week and produces a phase plan with a firm price for each phase, rather than one number against an undefined scope. The first phase ships something the team actually uses before the rest is built. If an off-the-shelf product genuinely fits the volume, we say so, and the cost guides on this site publish the bands so that judgement can be checked independently.
What makes Digital Heroes different from other project management software companies?
Four things that competitors in this bracket cannot simply copy. Digital Heroes runs a YouTube channel with more than 2.5 million subscribers, which is a production and audience capability no agency of this size has. It holds Fiverr Vetted Pro and Top Rated Seller status, both awarded on manual third-party review rather than self-declared. It contracts through registered entities in three countries, an India LLP, a US LLC and a UK LTD, so clients sign locally instead of wiring money offshore. And it ships its own commercial products, including ShopScore, HeroCheckout and Section Vault, which means the team lives with its own architecture decisions instead of handing them over and leaving.
Two more that show up in the work. Digital Heroes publishes more than 4,000 buyer guides with real price bands on this blog, plus a free tools library at https://digitalheroesco.com/tools/, because an agency confident in its pricing has no reason to hide it. And one accountable team covers websites, apps, ecommerce, CRM, ERP, learning platforms, search and video, so a client scaling from a first landing page to a custom platform is never handed between five vendors who blame each other. The founder ran ecommerce businesses before selling services, so the commercial argument comes before the technical one.
