TANK AND VESSEL ยท JOB COSTING SOFTWARE

CONTROLQORE FOR TANK AND VESSEL CONTRACTORS.

Generic accounting software can't keep an API 650 new-build book separate from an API 653 inspection and repair book, cost a confined-space entry day, or tell you how much billing is stuck behind an incomplete weld dossier. ControlQore can.

QUICK ANSWER

ControlQore for tank and vessel contractors is set up as two books inside one company: API 650 new construction on project cost codes, and API 653 inspection, repair, and alteration work on recurring service codes. Cost posts by phase, meaning engineering and welder qualifications, shop fabrication, field erection, welding and NDE, hydrotest, coatings and linings, and punch. Confined-space entry days carry their own code, with attendants, monitoring, and ventilation attached to it. Billing milestones are configured to the documentation an owner will require before releasing money, and the WIP schedule is produced monthly from cost-to-cost percentage complete.

The two books are the whole argument. New construction runs project economics with fabrication, erection, and hydrotest gates. The 653 side is condition-triggered work that recurs because the standard mandates inspection intervals, which makes it closer to a service annuity than to a project. Tracked as one book, both get mispriced, because the project work looks like it carries the shop when the service work is paying for it, or the reverse. Two P&Ls inside one company, built on the same cost code spine, price each side honestly and show which one is funding the other.

THE DEFINITION

WHAT IT IS.

ControlQore is a job costing and WIP platform for contractors that tracks cost by job and cost code, so a tank and vessel contractor can read cost by phase, meaning shop fabrication, field erection, welding and NDE, hydrotest, and coatings, with new construction reported separately from inspection and repair work.

WHAT YOU ARE DEALING WITH

WHERE IT GOES WRONG.

01

One Blended Book for Two Businesses

The trade splits along its standards. API 650 governs new welded-tank construction, meaning plate erection, weld examination, and hydrostatic testing, and it runs project economics. API 653 governs the in-service side, meaning mandated inspection intervals, evaluations, repairs, alterations, and reconstructions, which produces condition-triggered work that recurs. An operator tracking both as one book misprices both, and the recurring side is usually the stability the project side is borrowing against without anybody being able to prove it.

02

Payment Gated by a Dossier Nobody Costed

The paperwork is the paycheck. Welder qualifications have to be current under the ASME Section IX six-month continuity rule, weld maps and traceability packages gate acceptance, and NDE sampling has an economics of its own. Then there's the hydrotest, which on a tank means filling the structure with water: sourcing it, holding it, and disposing of it, a logistics event standing between substantial completion and the check. When none of that carries a cost code, the contractor can't say what an incomplete dossier is holding up.

03

Turnaround Windows Priced at Straight Time

Repair and alteration work often runs inside owner shutdowns and turnarounds. Every trade compresses into the same fixed window, premium-time and after-hours labor is the plan rather than the exception, and schedule overrun costs the owner enough that liquidated exposure and acceleration terms both sit in the contract. A bid priced at straight time in that window is a bid that pays the compression out of its own margin, and standby on a unit released late has no record behind it.

04

Confined-Space Days With No Cost Code

In-service work happens inside vessels. Permit-required confined-space entry brings a daily compliance class with it: entry permits, attendants, atmospheric monitoring, ventilation, and rescue provisions. Internal coatings and linings add surface work and cure windows that control the schedule for everybody else on the job. Carried explicitly per entry-day, it's a cost the bid recovers. Absorbed into general field labor, it's the margin, and no monthly statement will separate the two.

HOW SPM SETS IT UP

WHAT WE BUILD.

Two Divisions on One Cost Code Spine

SPM configures API 650 new construction and API 653 inspection and repair as separate divisions in ControlQore, reporting on the same cost code spine so the two are comparable. Each division carries its own P&L, its own overhead allocation, and its own margin history, which shows which side is funding the shop. Tank and vessel contractors at $1M to $5M net 7 percent before taxes on the SPM 48-trade dataset against a CFOS target of 10.5 percent, and the gross margin and overhead benchmarks for this trade are derived from the nearest comparable trade rather than measured on tank builders, which is one more reason each division needs numbers of its own.

Cost Codes by Fabrication and Field Phase

Cost codes follow the work: engineering and welder qualifications, plate procurement, shop fabrication and rolled shells, knock-down and freight, field erection, welding and NDE, hydrotest, coatings and linings, and punch. Labor, material, and subcontracted testing post to the phase that consumed them. The shop-fabrication and field-erection split then reports as two economies rather than one average, which is the same problem structural steel has and the same fix.

Billing Gated to the Documentation, Not the Calendar

SPM configures billing milestones against the documentation an owner will release money for: qualifications current, weld maps complete, NDE records accepted, hydrotest passed. The hydro goes on the 13 week cash flow forecast as its own event, with water sourcing, hold time, and disposal scheduled, because it's the last thing between substantial completion and payment. Retainage to acceptance is tracked separately so nobody mistakes it for collectible receivables.

The Window Priced and the Standby Documented

Turnaround work gets its own pricing class in ControlQore: premium-time and after-hours labor as the baseline rather than an add-on, acceleration terms read before signing, and a standby code for the days the unit isn't released when the schedule said it would be. Those standby hours get logged daily with the cause written down, at burdened cost. That record is what a compensable delay is built from, and it has to exist while the outage is still running.

Entry-Day Costing and Monthly WIP

A confined-space entry-day code carries the permits, attendants, monitoring, ventilation, and rescue provisions for every internal day, so the compliance class is priced in the next bid rather than discovered in the next P&L. The WIP schedule is produced monthly from cost-to-cost percentage complete by job and by division. Underbilled positions, meaning work performed but not yet billed, trigger a corrected pay app, and overbilled positions flag jobs where billing has outrun the documentation behind it.

COMMON QUESTIONS

FREQUENTLY ASKED.

Because they're different businesses wearing one company logo. API 650 new construction runs project economics with fabrication, erection, and hydrotest gates, while API 653's mandated inspection intervals generate condition-triggered repair work that recurs. Separate divisions in ControlQore give each one its own P&L and overhead allocation, which shows which side carries the shop and lets each be priced on what it costs and not on a blended average.
Billing milestones are configured to the documentation and not to a calendar date: qualifications current under the ASME Section IX six-month rule, weld maps and traceability complete, NDE records accepted, hydrotest passed. ControlQore reports what's complete and what's pending against each milestone, so the contractor can see how much billing is sitting behind missing paperwork. The hydrotest itself sits on the 13 week forecast as a scheduled event with water sourcing, hold, and disposal costed.
An entry-day code carries the whole daily compliance class: permits, attendants, atmospheric monitoring, ventilation, and rescue provisions. Crews log internal days against it, and coating and lining cure windows are tracked as schedule constraints on the same job. Once a year of entry-days is coded, the contractor has a per-day cost to bid internal work with, which is the difference between recovering the compliance apparatus and donating it.
60 days from engagement start to live job costing with WIP reporting. The tank-specific setup covers the two-division structure for API 650 and API 653 work, the fabrication and field phase cost code build, documentation-gated billing milestones, turnaround pricing and standby codes, the confined-space entry-day code, and historical data migration from QuickBooks. Most clients are fully operational in ControlQore within 60 days.
Three tiers, and which one you are in depends on how much of the work you want off your desk. Core is where you stop guessing: job costing built against the way you estimate, a 13 week cash forecast, monthly WIP, and a monthly meeting that ends in decisions, while your bookkeeper keeps doing the books. Executive is where you stop touching the books, because we run the bookkeeping and the controllership as well. Strategic is where every job shows its margin while it is still running, because the job costing and WIP platform is set up and managed for you. No payroll. No scope gaps.
