A board can approve a special assessment perfectly and still collect it badly. The vote is a governance question. Getting the money in is a cash-flow question, and the two have different right answers.
The mistake boards make is treating the payment structure as a courtesy rather than a design decision. How owners are allowed to pay determines how much of the assessment actually arrives, how long it takes, and how many households end up in collections over a bill they were willing to pay but could not pay that month.

Lump sum, installments, or both
Lump sum is the cleanest option on the board's side. One due date, one reconciliation, and the contractor gets paid without a bridge. It works when the per-home number is small enough to sit inside a normal household month, which in practice means a few hundred dollars rather than a few thousand.
Installments collect more of a large assessment, and they collect it from more households. A $2,400 assessment due in 60 days will produce a set of owners who simply cannot produce $2,400 in 60 days. The same $2,400 over twelve months is $200, which is a bill a household can plan around. The board trades a longer collection window for a higher collection rate.
Offer both, with an incentive on the lump sum, once the per-home number reaches four figures. A short discount or a fee waiver gives owners who can pay in full a reason to, which funds the project early, and the rest self-select into a schedule they can actually meet.
Two things make the installment option work rather than just exist. Set the schedule before the notice goes out, so owners choose from a real menu instead of negotiating one at a time. And make enrollment a form, not a phone call. Every step between "I need the plan" and "I am on the plan" costs you households.
The obligation many boards miss
Some states require associations to offer an installment option on delinquent assessments, and boards routinely learn this after they have already denied someone. Texas is the clearest example: Chapter 209 of the Texas Property Code, which governs subdivision property owners' associations rather than condominiums, requires an association above a stated lot count to adopt reasonable guidelines for an alternative payment schedule letting an owner pay a delinquent regular or special assessment in installments over a minimum additional period. Read the current text of the chapter for the thresholds and the terms; both have been amended more than once.
The point is not the Texas detail. The point is that your board's discretion over payment terms is narrower than your declaration alone suggests, and the way to find out is to read your state's association statute before you write the policy rather than after someone challenges it.

Handling hardship without inventing a policy per household
Hardship requests arrive one at a time, which is exactly why boards handle them inconsistently. Two owners in the same situation get different answers because two different board members took the calls, and the community notices.
Write the hardship policy before the first request. It needs four things: who reviews requests, what the applicant has to provide, what relief is available, and what the owner agrees to in return. Relief usually means a longer schedule or a deferred start rather than forgiveness, since forgiving one owner's share shifts it onto their neighbors.
Then apply it the same way every time and record the decision. Inconsistent treatment of similarly situated owners is one of the more reliable ways for a board to lose an argument it should have won.
Late fees and the line you should not cross
Charge the late fee your documents authorize, in the amount they authorize, on the schedule they authorize. Nothing else. Improvised penalties are routinely struck down when challenged, and they poison the collection either way.
Be careful about tone as well as amount. Association collection efforts are not always governed by the federal Fair Debt Collection Practices Act, but the practices that law prohibits are a reasonable floor for a board dealing with its own neighbors. The Consumer Financial Protection Bureau's debt collection resources describe what unfair and abusive collection looks like from the consumer's side. A volunteer board should not be anywhere near that line, and if collection reaches the point of liens or an attorney, get advice before the next letter goes out.
The tracking problem underneath all of this
Offer three payment options across 140 homes and you have created 140 separate schedules. Some owners pay in full. Some enroll and pay on time. Some enroll and miss month four. Two are on hardship terms nobody wrote down.
That state has to be correct on demand, because an owner will ask, a title company will ask at closing, and next year's board will inherit whatever answer you leave behind.
Which is the argument for a per-home ledger rather than a shared file. HOA-OS records each payment against the home that made it and keeps the running balance current, so the board reads the status instead of reassembling it. See how it works.
